In the triangle below, the three interior angles are labeled {eq}a {/eq}, {eq}b {/eq}, and {eq}c {/eq}. A triangle with interior angles labeled Other polygons have more than three interior angles. The number of interior angles in a polygon is always equal to its number of sides...
Fig.4 Triangle with labeled vertices (created using Geogebra) Next, draw a circle that will touch all vertices. This is the circumcircle. The center of this circle is called the circumcenter.Formula for Circumradius How to Find the Circumradius of a Triangle Applications of Circumradius Lesson...

The sides opposite the angles , , and (or , , ) are then labeled , , (or , , ), with these symbols also indicating the lengths of the sides (just as the symbols at the vertices indicate the vertices themselves as well as the vertex angles, depending on context). An triangle is ...
When working with right triangles, the same rules apply regardless of the orientation of the triangle. In fact, we can evaluate the six trigonometric functions of either of the two acute angles in the triangle in Figure 5. The side opposite one acute angle is the side adjacent to the other...
Solve the triangle with the given parts. α=39.7∘, γ=91.6∘, b=16.4 Properties of a Triangle A triangle is a polygon with three sides, three angles, and three vertices or corners. The following are the basic properties of a triangle- It has three side...
Before we come to the next Example, here is how we relate the sides and angles of a triangle:If an angle is labeled capital A, then the side opposite will be labeled small a. Similarly for angle B and side b, angle C and side c....
(often remembered with the mnemonic device "SohCahToa"). Solve for the missing angle by using the arcsin, arccos or arctan function of your calculator (usually labeled as "sin-1," "cos-1" and "tan-1"). For example, to find angle A given that side a = 3 and side b = 4, ...
It consists of three straight lines and three angles in between. Figure 1 shows how the sides and angles are usually labeled. Figure: Triangle A look into a book about geometry shows that many formulas for triangles exist: The values of a, b, c, tex2html_wrap_inline64 , tex2html_...
When you're done with and understand what a right triangle is and other special right triangles, it is time to go through the last special triangle --
