A 3-sided shape with one of the angles appearing like the corner of a square.
A right angled triangle has a base horizontal line with a start and end point (A,B).
A Perpendicular line rises from either of the end points perpendicular, or at a 90 degree angle from the base line. The third point )at the top of the perpendicular line) is called 'C'.
If the line was drawn from 'A', then join 'C' and 'B'.

Well, honey, the orthocenter of a right triangle is where all three altitudes intersect. In the case of a right triangle, the orthocenter coincides with one of the vertices, specifically the right angle vertex. So, grab your ruler and draw those altitudes to find that sassy orthocenter right at the corner of the right angle.
Such a triangle would presumably have one right angle, and two acute angles. A right angle has a measure of 90 degrees; an acute angle has a measure of less than 90 degrees. Since both of the other two angles in a right triangle must be acute angles, you'd think at first that every right triangle must be a right acute triangle. But when you go and look up the definition of an "acute triangle", it turns out to be a triangle in which all three angles are acute. So the fact is that there's no such thing as a right acute triangle, because the 90-degree angle in a right triangle is not acute.
180, just like every other triangle. the actual right angle is 90 and the other to angles equal 90
well you know what a right angle looks like? well its not half of that. however half of a right angle is 45 degrees so close to 42
-- Like every triangle, a right triangle has three interior angles.-- Unlike any other triangle, one of the angles in a right triangle is a right angle.The other two are both acute angles.-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]
