To solve this, use the fact that the sum of all three angles, in a triangle, is 180 degrees.
The 3 interior angles of any triangle add up to 180 degrees
By measuring them with a protractor will confirm that the 3 acute angles of a triangle add up to 180 degrees.
It means to find all of its sides and angles.
You will also need the angles so that you can use the Isosceles Triangle Theorems to solve for the base of isosceles triangle when only two sides are given.

A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.
By measuring them with a protractor will confirm that the 3 acute angles of a triangle add up to 180 degrees.
It means to find all of its sides and angles.
Alternate angles have the same measure, so there is nothing to solve!
you can use the sine, cosine, tangent formula.
By using the cosine rule in trigonometry the angles of the triangle can be worked out.
You will also need the angles so that you can use the Isosceles Triangle Theorems to solve for the base of isosceles triangle when only two sides are given.
A spherical triangle is not a question or a puzzle that you can solve, or even slove! You need to specify what information you have and what you wish to solve for: angles, lengths of sides, perimeter, area and so on.
To figure out what the measure of the base angles in an isosceles triangle are, it is important to first understand several things about an isosceles triangle. 1. A triangle has 180 degrees. 2. An isosceles has two equal sides, which means that it also has two equivalent angles. 3. In knowing at least any one angle of an isosceles triangle, it is possible to figure out the other two. Since the base angles are unknown in this question, and they are equivalent to one another, it is a simple algebraic problem. 180 - 70 = 2A 180 is the number of degrees in a triangle 70 is the number of degrees taken up by angle C, with angles A and B being the equivalent base angles. 2a is the double of one base angle. Let's solve. 180 - 70 = 2A 110 = 2A 110/2 = A 55 = A The measure of each base angle is 55.
a triangle has 180 degrees. So say if 2 angles are 50 and 40 u add them together and get 90 Then subtract 90 from 180 and get 90 and the other angle is 90 same thing goes for quadrialterals which are 360.
