Plane Geometry Answer 1

Plane Geometry Answer 1:

1. If one leg of a triangle is 5cm and the other leg is 12cm, what is the measurement of the hypotenuese of the triangle?

A. 5Ö12cm

B. 12Ö5cm

C. Ö17cm

D. 13cm

E. 17cm

The correct answer is D.

For any right triangle with sides A, B, and C, you need to remember this formula:

ÖA² + B² = C

In other words, the length of the hypotenuse (represented by side C) is equal to the square root of the sum of the squares of the other two sides of the triangle.

So we can substitute the values into the formula in order to find the solution for this problem:

ÖA² + B² = C
Ö5² + 12² = C
Ö25 + 144
Ö169
13cm
