Question

practice with special right triangles.
each leg of a 45°-45°-90° triangle measures 14 cm. what is the length of the hypotenuse?
○ 7 cm
○ $7\sqrt{2}$ cm
○ 14 cm
○ $14\sqrt{2}$ cm

Explanation:

Step1: Recall 45-45-90 triangle rule

For a 45°-45°-90° triangle, hypotenuse = leg length $\times \sqrt{2}$

Step2: Substitute given leg length

Leg length = 14 cm, so hypotenuse = $14 \times \sqrt{2}$

Answer:

14$\sqrt{2}$ cm
