WebOct 3, 2024 · Multiply the number of triangles you created by 180. Since there are 180 degrees in a triangle, by multiplying the number of triangles in your polygon by 180, you can find the sum of the interior angles of your polygon. [8] For example, since you divided your hexagon into 4 triangles, you would calculate. WebIn this activity, students will use sine, cosine, and tangent functions to find missing angle measures in right triangles. There is a total of 15 problems. In the first 9 problems, the students are given right triangles with two side lengths and a missing angle. There are 3 problems each requiring sine, cosine and tangent.

Triangles - Equilateral, Isosceles and Scalene
WebThere are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3 , 2 or no equal sides/angles: Equilateral Triangle WebExample #1 (No Triangles) Given A = 42 , a = 3, b = 8 Since A = 42 < 90 and a < b, we calculate the value of sin B using the Law of Sines: 3 sin42° = 8 sin𝐵 yields that sin B = 1.784 which is greater than one (recall that -1 < sin B < +1). Hence, there are no possible triangles and nothing to solve for. Example #2 (Two Triangles) WebScalene Triangle. No equal sides. No equal angles. How to remember? Alphabetically they go 3, 2, none: Equilateral: "equal" -lateral (lateral means side) so they have all equal sides. Isosceles: means "equal legs", and we have two legs, right? Also i SOS celes has two equal "S ides" joined by an " O dd" side. chippy runcorn
