It still adds up to 360°The Interior Angles of a Quadrilateral add up to 360°Because there are 2 triangles in a square ...The interior angles in a triangle add up to 180° ... and for the square they add up to 360° ... because the square can be made from two triangles!Pentag...
We can quickly work out the sum of the three interior angles of a triangle by considering a triangle with an extra straight line drawn parallel to the base of the triangle and touching the triangle's top corner, as in the diagram below. To find the sum of the interior angles a + b +...
Every triangle has three sides and three angles on the inside. These angles add up to 180° for every triangle, independent of the type of triangle. In a right triangle, one of the angles is exactly 90°. Such an angle is called a right angle. To calculate the other angles, we need ...

Angles in a triangle? There are 3 angles in a triangle and they add up to 180 degrees Angles of isoceles triangle? The interior angles of a triangle add up to 180. So a triangle with 3 equal sides (or angles) will have 60-degree angles. * * * * * True, but the question is ab...
In a right-angled triangle, the two non-right angles are complementary. Why? Because the sum of angles in a triangle is 180°, and one angle is already 90°, the remaining two angles must add up to 90°When two angles add to 90°, we say they "Complement" each other. Complementary...
