right angle triangles have right angles, but there is no such thing as a right angle kite
No. An acute angle is an angle smaller than 90 degrees. A right angle is an angle that is exactly 90 degrees
To show a right angle you have to mark the inside corner so that it looks like a square.
4 INSIDE right angles. and 4 (outside) REFLEX right angles.
The angle bisectors always intersect inside the triangle. (This is not true for altitudes and right bisectors.)
