A triangle where one of the three sides is exactly 90 degrees is called a right-angled triangle. The side opposite to this 90-degree angle has the longest side length, it is called the hypotenuse. If any two interior angles of a triangle are similar to any two interior angles of another...
While you often see these three types of triangles identified by the lengths of their sides, they can also be categorized by their angles. It works exactly the same way: When all the angles are the same 60 degrees, it’s anequilateral triangle. Technically, it’s called an equiangular tria...

Cross-check by measuring the angles with the protractor. If each angle measures 60 degrees, then the triangle is equiangular and--by definition--equilateral. Label the triangle "isosceles" if only two sides are equal. Remember that the angles contained by the two equal sides (the base angles...

One type of triangle is a right triangle; that is, a triangle with one right (90 degree) angle. The right angle is usually marked with a small square in that corner, as shown in the image. The Greek mathematician Pythagoras is credited with creating a mathematical equation to find the le...

When we need to work with a30- or a60-degree angle, the process is similar to the above, but the set-up is a bit longer. (A30°angle is equivalent to an angle ofradians; a60°angle is equivalent to an angle ofradians.) For either of the angles, this is the triangle that we star...
