Final answer:
To find the measure of each angle in a triangle, you need to use the property that the sum of the angles in a triangle always equals 180 degrees. By knowing this and the type of triangle, you can calculate the measure of the missing angles.
Step-by-step explanation:
To determine the measure of each angle in a shape, we must first know the type of shape and its characteristics. In this case, we are dealing with a triangle. A triangle is a three-sided figure lying on a plane. An important property of a triangle is that the sum of its interior angles always adds up to 180 degrees. This is a fundamental principle that holds true for all triangles, regardless of their type (whether they are scalene, isosceles, or equilateral).
Let's take a look at a simple example. Suppose you have an isosceles triangle, which has two angles that are equal. If one of the equal angles is 50 degrees, then the sum of these two angles will be 100 degrees (50 degrees + 50 degrees). The remaining third angle must be such that the sum of all three angles equals 180 degrees. Therefore, the third angle will be 80 degrees (180 degrees - 100 degrees).
