Question

What is the answer please help me please ?

Answer 1

Answer:

  3.  isosceles, acute

  5. scalene, obtuse

Step-by-step explanation:

3. Two (and only two) sides are the same length (and their opposite angles are the same measure), so the triangle is isosceles. All angles are less than 90°, so the triangle is acute.

__

5. All angles have different measures, so the triangle is scalene. The largest angle is greater than 90°, so the triangle is obtuse.
