The exterior angle theorem is Proposition 1.16 in Euclid's Elements, which states that the measure of an exterior angle of a triangle is greater than either of the measures of the remote interior angles. This is a fundamental result in absolute geometry because its proof does not depend upon the parallel postulate. In several high school treatments of geometry, the term "exterior angle theorem" has been appli…

WebWe can learn a lot about regular polygons by breaking them into triangles like this: Notice that: the "base" of the triangle is one side of the polygon. the "height" of the triangle is the "Apothem" of the polygon. Now, the area of a triangle is half of the base times height, so: Area of one triangle = base × height / 2 = side × apothem / 2. WebExterior Angle The Exterior Angle is the angle between any side of a shape, and a line extended from the next side. Another example: When we add up the Interior Angle and …

WebApr 7, 2024 · In a triangle, the exterior angle is always equal to the sum of the interior opposite angle. This property is known as exterior angle property. Any two triangles will be similar if their corresponding angles tend to be congruent and the length of their sides will be proportional. The area of a triangle is ½ x base x height.
