What is side angle angle theorem?

Any two angles of a triangle determine the third angle. As a result, the side angle angle theorem is equivalent to the angle side angle theorem.


What is the Hinge Theorem is based on?

SAS Inequality Theorem the hinge theorem states that if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first triangle is longer than the third side of the second triangle.

It is Pythagoras' theorem


Can the Third angle theorem prove that the ASS triangle is congruent?

No, because the third-angle theorem requires that you know two angles of each of the triangles. Assuming ASS, you only know one angle. In fact, two triangles may have the same ASS and not be congruent. See if you can make two non-congruent triangles with Angle 60 deg, Side 10, and Side 9.


What is the hinge theorem?

The hinge theorem in geometry states that if two sides of one triangle are congruent to two sides of another triangle, and the included angle of the first is larger than the included angle of the second, then the third side of the first triangle is longer than the third side of the second triangle

Length of third side of triangle?

for known 2 sides and included angle, use cosine theorem a2=b2+c2-2bc cos(angle A) for right-angled triangles, use Pythagoras's theorem a2+b2=c2


What is the Straight angle theorem?

A straight angle is an angle of 180 degrees


What is the 30-60 right angle theorem?

90


What is the formula of Pythagorean Theorem?

c2 = a2 + b2 Where "a" and "b" are the lengths of the sides of a triangle that meet to form a right angle (90 degree angle) and "c" is the third side, the hypotenuse


Why can't the Pythagorean theorem be used without a right angle?

The Pythagorean theorem is actually the law of cos, where the angle is 90.
