Question

given the following three angel measure of a triangle, does the triangle exist Euclidean geometry,spherical geometry, or neither?​

Answer 1

A

Explanation:

Euclidean geometry is the normal geometry that we normally study in class. The sum of 3 angles in a triangle is 180 degrees.

In spherical geometry, spheres are used to plot points. The sum of 3 angles of a triangle always exceed 180 degrees.

Given, the 3 angles, lets add up:

47 + 26 + 107 = 180 degrees

This will fall into "euclidean geometry".

Correct answer is A
