5-52.

For each triangle below, use your triangle shortcuts from this lesson to find the missing side lengths. Then find the area and perimeter of the triangle. Homework Help ✎

What special triangles can you use for each part?
Find the lengths of the missing sides using the special triangle relationship you chose.

Perimeter Calculation

$\text{Perimeter }= 2 + \sqrt{2} + \sqrt{2}$

$2 + 2\sqrt2 \text{ m}$

Area Calculation

$\text{Area }=\frac{1}{2}\cdot b\cdot h$

$=\frac{1}{2}\sqrt{2} \cdot\sqrt{2}$

$=\frac{1}{2}\cdot (2)$

$\text{Area}=1$ sq. m
