WebbA triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the … Webb18 nov. 2015 · It is a special case of the markers that denote the angle between two rays. For example, you could use an angle arc (shown as theta in your image) and beside it specify that its value is 90. Those two symbols would be equivalent.
