Answer:
Isosceles
Explanation:
Pre-Solving
We are given a triangle. We know that the angles have a measure of 45°, 45°, and 90°.
We also know that the sides of the triangle are 3.2, 3.2, and 4.5 units.
We want to classify this triangle.
Solving
A scalene triangle has all of its sides and angles as different values.
An isosceles triangle has 2 of its sides as the same value, and 2 of its angles as the same value.
An equilateral triangle has all of its sides as the same value, and all of its angles as the same value.
Looking at the side lengths and angle values we are given, we can see that we have 2 angles that are the same value (45°), and 2 sides that are the same value (3.2 units).
Therefore, we have an isosceles triangle.
