What are the proportional properties of proportional line segments, and what are the basic propertie

Basic properties of proportions: a b = c d ad=bc proportional properties of proportions: a b = c d (a + b) b = (c + d) d Note: add the denominator to the numerator).

Proportional properties of proportions: a b=c d (a-b) b=(c-d) d proportional properties: if a b=c d=...=m/n(b+d+…+n≠0), then (a+c+...+m)/(b+d+…+n)=a/b=c/d…=m/n

Inverse proportionality.

Properties: a b = c d b a = d c

Proportional proportional properties: if a b=c d then a c=b d proportional line segments. If the 4 line segments are proportional.

The 4 line segments are called proportional line segments.

Parallel. Divide the line segments proportionally].

2. If you cut 3 parallel lines in a straight line, the corresponding line segments are proportional.

When L1, L2, and L3 are parallel to each other, ab:bc=de:ef,ad:be=be:cf

Apply] the scale of the map.

Proportional nature. Basic properties of proportions: a b = c d ad=bc proportional properties of proportions: a b = c d (a + b) b = (c + d) d Note: add the denominator to the numerator).

Proportional properties of proportions: a b=c d (a-b) b=(c-d) d proportional properties: if a b=c d=...=m/n(b+d+…+n≠0), then (a+c+...+m)/(b+d+…+n)=a/b=c/d…=m/n

Inverse nature of proportion: a b=c d b a=d c proportional nature: if a b=c d then a c=b d proportional line segment: if the 4 line segments are proportional, then the 4 line segments are called proportional line segments.

Parallel lines divide segments proportionally].

2. If you cut 3 parallel lines in a straight line, the corresponding line segments are proportional.

When L1, L2, and L3 are parallel to each other, ab:bc=de:ef,ad:be=be:cf hope it helps you!
