Exterior and Interior Angles of Triangles What are the Triangles? A triangle is a simple closed curve which is created by three line-segments. In geometry, any three points, specifically non-collinear, form a unique triangle and separately, a unique plane. The basic elements of the triangle ar...
by dividing it up into triangles with lines connecting the vertices.For example, the hexagon shown opposite has been divided into 4 internal triangles.The sum of all the interior angles of the hexagon is equal to the sum of all the angles in each triangle, so:sum of interior angles =4 ×...
We are given that an exterior angle of a triangle is 100∘ and that the two interior opposite angles are equal. We need to find the measure of these two angles. Step 2: Label the triangleLet’s label the triangle as ABC where:- C is the vertex where the exterior angle is formed....
