When triangles are similar, they could be congruent. However, they do not have to be congruent in order to be similar. So I guess the answer is not always.

right angles. Since the triangles are similar, write the x 135 proportion and solve for x: 90(x) = 120(135); x = 180 ft . 120 90 ' 16. The triangles are similar because a pair of congruent angles is given and the two right angles are congruent by AA— Postulate. 5 ft 6 in. = 66 in. Since the triangles are similar, we can write x 10 the proportion
If you can show that two triangles are congruent, then their corre-sponding parts are also congruent. CPCTC: Corresponding Parts of Congruent Triangles are Congruent We will use this shortcut when writing Two-Column Proofs. In a two column proof, statements are made in the left column, and justifi-cations for those statements are on the right. 1.
Section 11.3: Corresponding Parts of Similar Figures Questions to ponder… 1.If two figures have the same number of sides and the corresponding angles are congruent, does this mean that a pair of corresponding sides are either congruent or proportional?

Triangles are still waiting for their big break into the movie business, and of the three, Oompa-Loompas are the... SSS and SAS If two triangles have edges with the exact same lengths, then these triangles are congruent.
Review of Similar Triangles. Definition Two triangles ABC and A'B'C' are similar if the three angles of the first triangle are congruent to the corresponding three angles of the second triangle and the lengths of their corresponding sides are proportional as follows. AB / A'B' = BC / B'C' = CA / C'A' Angle-Angle (AA) Similarity Theorem

MCC9-12.G.CO.10 Prove theorems about triangles. Theorems include: measures of interior angles of a triangle sum to 180 degrees; 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.
Congruent Shapes. If two shapes are exactly the same - that is, they are the same size, they have the same side lengths, and the same angles - then we say they are congruent.. For most shapes it's as simple as seeing if they are the same, but for triangles there are 4 rules you need to learn.. Make sure you are happy with the following topics before continuing:
The next theorem shows that similar triangles can be readily constructed in Euclidean geometry, once a new size is chosen for one of the sides. It is an analogue for similar triangles of Venema’s Theorem 6.2.4. Theorem C.2 (Similar Triangle Construction Theorem). If 4ABC is a triangle, DE is a segment, and H is a half-plane bounded by ←→
