The functions of cartilage in your skeletal system include  cushioning your joints and creating passages for air when  flexibility is required. Cartilage cushions the areas â¦ between your  vertebra and joints.
exists and is an alternate of . LL Congruence theorem says: If the two legs of one right triangle are congruent to the two legs of another right triangle, then the two right triangles are congruent.
Since the sum of the angles in a triangle must be 180 o, this implies that the other two angles in a right triangle must add up to 90 o. Many special trigonometric relationships between the sides and the angles emerge as a result of this special 90 o angle. One of these relations is the so called Pythagorean Theorem. In this special type of triangle, two sides are equal to each other. 2  One can prove-as you probably did long time ago in your geometry class-that the the angles opposite to these two equal sides are also equal to each other.
