Question

Triangle ABC is an isosceles right triangle with the measure of angle A equal to 90 degrees. The length of segment AC is 6 cm. What is the area of triangle ABC, in square centimeters

Answer 1

18 cm^2

Explanation:

If AC is considered the base of the triangle, then AB will be the height. Since the triangle is isosceles, these measures are the same.

A = (1/2)bh = 1/2(6 cm)(6 cm) = 18 cm^2

The area of triangle ABC is 18 square centimeters.
