Question

Be able to identify postulates used to prove the two triangles are similar. Be able to describe how they are applied. Be able to draw a picture to help with your description. Prove the Pythagorean Theorem using similar triangles. Prove the Triangle Proportionality Theorem and/or its converse. Use a diagram to aid in your proof. Find the indicated lengths in the figures below. How can similar triangles be used to indirectly measure the height of objects that are difficult to measure? Give an example and explain the steps you would use in your example. (Any and all help is appreciated. I don't need diagrams or anything done, but I do need this urgently! Thank you so so much!!)

Answer 1

Be able to identify postulates used to prove the two triangles are similar.
-Angle-Angle (AA) Similarity Postulate
-Side-Side-Side (SSS) Similarity Theorem
-Side-Angle-Side (SAS) Similarity Theorem

Be able to describe how they are applied.
-AA Postulate - If two angles of one triangle are congruent to two angles of another, then the triangles must be similar.
-SSS Theorem - If the lengths of the corresponding sides of two triangles are proportional, then the triangles must be similar.
-SAS Theorem - If an angle of one triangle is congruent to an angle of a second triangle and the lengths of the sides including these angles are proportional, then the triangles must be similar.
those are the first two parts good luck on the rest of it, have a nice day
