Limits

When it comes to calculus, limits are considered to be a very important topic of discussion. The main importance of limit lies in expressing the value of a function as it gets closer to a certain value. Also, limits can help you to understand other topic…

Question

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).

Chapter 1.4, Problem 25WE

To determine

To find: the approximate measure of each angle, and to compute the sum of the three measures.

Expert Solution & Answer

Answer to Problem 25WE

The sum of the three angles of the triangle are equal to 180° .

Explanation of Solution

Consider the protractor to find the measure of each angle in these two triangles.

As it can be seen form the above two figures it can be observed that the sum of the three angles of the triangle are equal to 180° .

Take these two triangles, one is right angle triangle and other is equilateral triangle so one can take any type of triangle.

Therefore, one will find that the sum of the three angles will always be equal to 180° .
