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.
Theorems include: measures of interior angles of a triangle sum to 180Â°; base angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of a triangle meet at a point. The student will: x prove that the sum of the measures of the interior angles of any triangle is 180 degrees. x prove that the base angles of an isosceles triangle are congruent. x prove that the segment joining the midpoints of two sides of a triangle is parallel to the third side and half the length of the third side. x prove that the medians of a triangle meet at a point. x use theorems about triangles to prove claims about geometric figures .
