Question

1 . A right triangle has side lengths 3 cm,

4 cm, and 5 cm.
a) Draw the triangle.
b) A similar triangle has hypotenuse
30 cm long. What is the scale factor?
c) What are the lengths of the legs?

Answer 1

b. 6
c. 3 and 4

Explanation:

A. you can do that, just a right triangle with side lengths 3, 4, and the hypotenuse length of 5
b. the hypotenuse goes from 5 to 30, 30 / 5 = 6 so the scale factor is 6
c. the legs of a right triangle are the 2 lines that are intersected by the hypotenuse, so if the hypotenuse is 5, the legs are 3 and 4
