Since X and, $$ \angle J $$ are remote interior angles in relation to the 120° angle, you can use the formula. $$ 120° = 45° + x \\ 120° - 45° = x \\ 75° = x. $$ Now, since the sum of all interior angles of a triangle is 180°. You can solve for Y. This worksheet shows students how to find the area of a triangle. There are 9 practice problems. Triangles measurements have two-digit numbers, decimals, and fractions. 1. Warmup: Define the postulate below. Also, mark the triangles appropriately. 2. Angle Side Angle (ASA) Postulate: 3. Angle Angle Side (AAS) Theorem a. If two angles and the non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the triangles are congruent. Ex. 3: Practice with SAS: Determine if the two triangles are similar by SAS. a. ∆LNM and ∆JNK b. ∆CDB and ∆CEA. Ex. 4: Mixed Practice: Determine whether the triangles are similar. If they are, state what postulate or theorem you used and write a similarity statement. 1.) 2.) 3.) Show that the two triangles are similar.
