WebbBroadly, right triangles can be categorized as: 1. Isosceles right triangle: In this triangle, one interior angle measures 90°, and the other two angles measure 45° each. It is also known as a 45-90-45 triangle. This is an isosceles right triangle, with the sides AB and AC equal and ∠ B measuring 90°. Here, ∠ A and ∠ C measure 45 ...

WebbA special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist.
