HELPP HELP HELP PLS !!! Below are two triangles with their side lengths shown. Answer the questions about each triangle. 18 15 1

NNADVOKAT [17]

Answer:

Triangle 1's answers:

9² + 12² = 15²

15² = 225

Right Triangle

Trangle 2's answers:

6² + 15² = $\sqrt{261}$

18² = 324

Obtuse Triangle

Step-by-step explanation:

The answers to number 1 for each triangle are solved exactly how they are written :).

The number 2s of each triangle are just numbers squared. 15 squared is 225. 18 squared is 324.

Triangle 1 is a right triangle because the angle is a right angle and the triangle can be solved perfectly using the Pythagorean Theorem.

Triangle 2 is an Obtuse Triangle because one side has a way larger angle than the other two angles.

Hope it helps!
