WebBroadly, 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 … WebIn any triangle, two of the interior angles are always acute (less than 90 degrees) *, so there are three possibilities for the third angle: . Less than 90° - all three angles are acute and so the triangle is acute. Exactly 90° - it is a right triangle Greater than 90° (obtuse): the triangle is an obtuse triangle In the figure above, drag the vertices around and try to create all 3 ...
