One of the inner angles in an isosceles triangle is 50 degrees, find the degrees of the other two an

1.50 degrees is the bottom angle.

Then the other bottom angle is 50 degrees, and the top angle is 80 degrees.

The degree is the top angle, then the other two bottom angles are 65 degrees

If this inner angle of the isosceles triangle is the apical angle, then the other two angles have degrees of 65 degrees.

If this inner angle of the isosceles triangle is the base angle, then the other two angles have degrees of 50,80 degrees, respectively.

If the 50-degree angle is the top angle, then the other two angles are 65 degrees, and if the 50-degree angle is the bottom angle, the other bottom angle is 50 degrees, and the top angle is 80 degrees.

There are two cases: the first one angle = 50° and the other two angles are both 65°

The second one is 50° and the other is 80°

If it is a top angle, the other two corners are 65°; If it is a bottom angle, the other base angle is 50° and the top angle is 80°

Solution: Pay attention to two situations.

When the apex angle is 50°.

The other two corners are the bottom angles, both 65°;

When the base angle is 50°, the other two angles are the base angle and the top angle, which are 50° and 80°, respectively

When the apex angle is 50°.

Bottom angle = (180-50) 2 = 65

When the base angle is 50°.

Top angle = 180-50-50 = 80

The sum of the inner angles of the triangle is 180 degrees, and the base angles of the isosceles triangle are equal.

There are two answers to your question:

1.If this angle is the top angle, then.

180-50) 2=75 degrees.

The other two angles are: 75 degrees, 75 degrees.

2.If this angle is the bottom angle, then.

180-50*2=80 degrees, the other two angles are: 80 degrees and 50 degrees.

1.The sum of the inner angles of the triangle is 180 degrees! The bottom angles of the isosceles triangle cavity are equal!

If this angle is the apex angle, then (180-50) 2=75 degrees and the other two angles are: 75 degrees, 75 degrees 2If this angle is the bottom angle, then 180-50*2=80 degrees The other two angles are J or shirt:

80 degrees, 50 degrees ps: There are two answers!

60 degrees. If this angle is the top angle, the two bottom angles are traced, etc., 120 2=60 degrees.

If this angle is the bottom of the Tong angle, then the other bottom angle is also 60 degrees, and the top angle is 180-60x2 = 60 degrees.

If the apex angle is 80°

Then the bottom angle of the nucleus is: (180°-80°) 2=50°Therefore, the other two angles are: 50°, Nazhou 50°, if the bottom angle is 80°

then the other base angle is 80°

The apex angle is: 180°-80°-80°=20°

Therefore, the other two angles are °

1.If 70° is the apex angle of an isosceles triangle, then both bottom corners are sailworthy.

2.If 70° is one of the base angles of an isosceles triangle, then another base angle is also 70° of Changchen hail, and the third angle of the triangle is.

65 degrees, 65 degrees, or 50 degrees, 80 degrees. Here's why:

1. When the 50-degree inner angle is the apex angle, the number of the other two internal angles is: (180-50) 2=65 degrees.

2. When the 50-degree inner angle is the bottom angle, because it is an isosceles triangle, the number of the two base angles is the same, then the other inner angle is 50 degrees, and the top angle is 180-50-50=80 degrees.

This problem is solved by using the sum of the number of angles in the triangle to be 180 degrees.

The nature of the triangle.

1. The sum of the internal angles of the triangle on the plane is equal to 180° (the sum of the internal angles theorem).

2. The sum of the outer angles of the triangle on the plane is equal to 360° (the sum of the outer angles theorem).

3. On a plane, the outer angles of a triangle are equal to the sum of the two inner angles that are not adjacent to it.

Corollary: One outer angle of a triangle is greater than any of its inner angles that are not adjacent to it.

4. A triangle has at least two acute angles among the three inner angles.

5. At least one angle in the triangle is greater than or equal to 60 degrees, and at least one angle is less than or equal to 60 degrees.

6. The sum of any two sides of the triangle is greater than the third side, and the difference between any two sides is less than the third side.

7. In a right-angled triangle, if an angle is equal to 30 degrees, the right-angled side opposite by the 30-degree angle is half of the hypotenuse.

8. The sum of the squares of the two right-angled sides of a right-angled triangle is equal to the square of the hypotenuse (Pythagorean theorem).

Two possibilities When this inner angle is the top angle, then the other two angles are (180-50) 2=65 degrees When this inner angle is a base angle, then the other bottom angle is also 50 degrees, and the top angle is 180-50-50=80 degrees.

Two possibilities. When this inner angle is the apex angle, then the other two angles are (180-50) 2=65 degrees.

When this inner angle is a bottom angle, then the other bottom angle is also 50 degrees, and the top angle is 180-50-50=80 degrees.

If the angle of 50 degrees is the hail of the top angle, then the other two bottom angles are 65 degrees, and if the 50-degree angle is the bottom angle, then the other bottom angle is also 50 degrees, and the top angle is 80 degrees. Thank you.

180-50 = 130, 130 2 = 65 or 50 times 2 = 100, 180-100 = 80, 80 and 50 respectively(There are two answers to this question, depending on whether the inside angle of the triangle you are talking about is a low angle or a top angle.) ）
