Angles between adjacent sides of a triangle are referred to as interior angles in Euclidean and other geometries. Exterior angles can be also defined, and the Euclidean triangle postulate can be formulated as the exterior angle theorem. One can also consider the sum of all three exterior angles, that equals to 360° in the Euclidean case (as for any convex polygon), is less than 360° in the spherical case, and is greater than 360° in the hyperbolic case. WebObjectives. Students will be able to. find the measure of an angle in a triangle given the measure of two other angles, find the measure of an angle in a triangle by determining the measure of the other two angles from geometric properties, find an unknown angle related to an interior angle of a triangle using geometric properties.
