Quarter2 Independent Assignment #7 on Solving similar triangles

Front

What is the definition of similar triangles?

Back

Similar triangles are triangles that have the same shape but may differ in size. Their corresponding angles are equal, and the lengths of their corresponding sides are proportional.

What is the formula for finding the area of similar triangles?

Back

The area of similar triangles is proportional to the square of the scale factor.

Front

If the scale factor between two similar triangles is 4, how does this affect their areas?

Back

The area of the larger triangle will be 4^2 = 16 times the area of the smaller triangle.
