What do the markers on the sides indicate?
Right isosceles
Let's analyze the given triangle.
| Type | Sides |
|---|---|
| Scalene | No congruent sides |
| Isosceles | At least 2 congruent sides |
| Equilateral | 3 congruent sides |
Note that there are markers on two sides. They indicate that these sides are congruent. Knowing this, the triangle is isosceles. Now let's look at the angles.
| Type | Angles |
|---|---|
| Acute | 3 acute angles |
| Right | 1 right angle |
| Obtuse | 1 obtuse angle |
| Equiangular | 3 congruent angles |
Since ∠XYZ is a right angle, we can also classify the triangle as a right triangle. Therefore, △ XYZ is a right isosceles triangle.
