Proving triangle similarity edgenuity.
We will need to find the ratios for the corresponding sides of the triangles and see if they are all the same. Start with the longest sides and work down to the shortest sides. B C F D = 28 20 = 7 5. B A F E = 21 15 = 7 5. A C E D = 14 10 = 7 5. Since all the ratios are the same, A B C ∼ E F D by the SSS Similarity Theorem.

The Pythagorean Theorem is just a special case of another deeper theorem from Trigonometry called the Law of Cosines. c^2 = a^2 + b^2 -2*a*b*cos (C) where C is the angle opposite to the long side 'c'. When C = pi/2 (or 90 degrees if you insist) cos (90) = 0 and the term containing the cosine vanishes.
Example 1. Example 2. Proofs involving isosceles triangle s often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.

Angle Restrictions Based On Side Lengths. Isosceles triangles can be acute, Consider the triangles in the figure. , or obtuse. all the angles are less than 90°. Since TQ ≅ QS, P Q it’s an isosceles triangle. So, it’s an isosceles acute triangle. • PQR: This is a right isosceles triangle. SQP: Angle Q is an obtuse angle.
