But you can have a right angle, you can have a right triangle, that is isosceles.

In this article, we have given two theorems regarding the properties of isosceles triangles along with their proofs. The opposite side (BC) of the right angle, whose ends are touched by arms of the angle (AB & AC), is the hypotenuse. The longest side of the right triangle is the hypotenuse and the other two sides are height and the base. When the third angle is 90 degree, it is called a right isosceles triangle. Right angle triangle is a triangle in which one angle is 90. It has two equal angles, that is, the base angles. You obviously cant have a right triangle that is equilateral, because an equilateral triangle has all of their angles have to be 60 degrees. Some pointers about isosceles triangles are: It has two equal sides. 1D Line, Circular Arc, Parabola, Helix, Koch Curve 2D Regular Polygons:Įquilateral Triangle, Square, Pentagon, Hexagon, Heptagon, Octagon, Nonagon, Decagon, Hendecagon, Dodecagon, Hexadecagon, N-gon, Polygon Ring Or another way to think about is if I have a right triangle that is also isosceles.
