Anonymous users2024-02-15The sum of the inner angles of a triangle is 180 degrees, while an isosceles triangle.
The two base angles are equal, and the top angle is known to be 50 degrees, then the sum of the two base angles is 130 degrees, so one base angle is 65 degrees.

Anonymous users2024-02-14Since the two base angles of an isosceles triangle are equal, if one of the base angles is x degrees, then the other base angle is also x degrees.
Since the sum of the three interior angles of a triangle is 180 degrees, the following equation can be listed:
50 + x + x = 180
To simplify: 2x + 50 = 180
2x = 130
x = 65
Therefore, one base angle of this isosceles triangle is 65 degrees.

It is right that an equilateral triangle is a special isosceles triangle because an equilateral triangle is that all three sides are equal, and an isosceles triangle is that both sides are equal, so an equilateral triangle must be an isosceles triangle. An equilateral triangle is a triangle in which all three sides are equal; An isosceles triangle is a triangle with two equal sides, so an equilateral triangle is a special isosceles triangle, but an isosceles triangle is not a special equilateral triangle. >>>More
