List of triangle theorems
WebTriangles Triangle A triangle is a closed figure in a plane consisting of three segments called sides. Any two sides intersect in exactly one point called a vertex. A triangle is named using the capital letters assigned to its vertices in a clockwise or counterclockwise direction. For example, the triangle below can be named triangle ABC in a WebTriangles ABC and PQR are similar and have sides in the ratio x:y. We can find the areas using this formula from Area of a Triangle: Area of ABC = 12 bc sin(A) Area of PQR = 12 qr sin(P) And we know the lengths of the …
