Question

drag a vertex of the triangle to change its shape. double - click or double - tap a vertex or side to prevent it from changing.
problem: construct a triangle with interior angle measures of 45° and 45°. the third angle of the triangle is

Explanation:

Step1: Recall the sum of interior angles of a triangle

The sum of the interior angles of a triangle is \(180^{\circ}\).

Step2: Calculate the third angle

Let the third angle be \(x\). We know two angles are \(45^{\circ}\) and \(45^{\circ}\). Using the formula \(x + 45^{\circ}+45^{\circ}=180^{\circ}\), we can solve for \(x\).
