The 30-60-90 right triangle is a special case triangle, with angles measuring 30, 60, and 90 degrees. This free geometry lesson introduces the subject and provides examples for calculating the lengths of sides of a triangle.

en.wikipedia.org/wiki/Degree_(angle)

A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees. It is not an SI unit, as the SI unit of angular measure is the radian, but it is mentioned in the SI brochure as an accepted unit.

Several different angle breeds, or types, exist. You can figure out what breed of angle you have by its measure. The most common measure of an angle is in degrees. Here is a brief introduction to the four types of angles: Right angle. With this angle, you can never go wrong. The right angle is one of the most easily recognizable angles.

This page shows how to construct (draw) a 60 degree angle with compass and straightedge or ruler. This construction works by creating an equilateral triangle. Recall that an equilateral triangle has all three interior angles 60 degrees. We use one of those angles to get the desired 60 degree result. See the proof below for more details. A Euclidean construction.

(Note: "Degrees" can also mean Temperature, but here we are talking about Angles) The Degree Symbol: ° We use a little circle ° following the number to mean degrees. For example 90° means 90 degrees. One Degree. This is how large 1 Degree is . The Full Circle. A Full Circle is 360° Half a circle is 180° (called a Straight Angle) Quarter of ...

What Does a 45-Degree Angle Look Like? A 45-degree angle looks like the bisection of a right angle. If one constructs a right angle by drawing one axis horizontally and the other axis vertically, a 45-degree angle is halfway between a flat slope and a vertical slope.
