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...
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
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

Two sides, or two angles + one side.
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

It means to find all of its sides and angles.
you can use the sine, cosine, tangent formula.
Pythagorean theorum.
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.
