By measuring them with a protractor will confirm that the 3 acute angles of a triangle add up to 180 degrees.
Yes, because you know two angles so you can extremely easily calculate the third...
A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.
To solve this, use the fact that the sum of all three angles, in a triangle, is 180 degrees.
Because another triangle could have exactly the same angles, but its sides could all be twice as long, or 62 times as long etc. There are an infinite number of triangles that all have the same two acute angles. They're all similar to each other, but they're not congruent.
If its angles are 45, 45 and 90 degrees then it is an isosceles right angle triangle and its properties can be worked out using Pythagoras' theorem and trigonometry
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.

In a triangle, the sum of the three angles is always 180 degrees. This relationship can be used to solve geometric problems by finding the measure of one angle and then using the fact that the sum of all angles in a triangle is 180 degrees to find the measures of the other angles. This concept is helpful in solving various types of geometry problems involving triangles.

This is a homework question so I will not provide the answer because it is important that you do this yourself and understand how to solve the problem. However to help you do this you need to know that the internal angles of a triangle add up to 180 degrees.
If its angles are 45, 45 and 90 degrees then it is an isosceles right angle triangle and its properties can be worked out using Pythagoras' theorem and trigonometry

The 3 interior angles of any triangle add up to 180 degrees
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
First find 180 minus the vertex angle and divide that by 2 to get the other angles. Then solve the other sides by using sin(vertex angle)/base=sin(other angles)/other sides.
