4. a) Draw an example of two non congruent triangles that satisfy the following conditions. If not possible, explain why. (1) The two triangles have congruent corresponding angles. (ul) The two triangles have congruent corresponding angles, and one pair of sides (not corresponding sides) congruent. () The two triangles have congruent corresponding angles, and two pairs of sides (not corresponding sides) congruent. b) (i) is the statement "If A ABC A DEF, then 2CAB ELFED", true or false? Clearly explain...
A If Angle ABD is congruent to Angle EEB, then two pairs of triangles are congruent in this figure. CBB Concepts used: Isosceles triangle, Angles opposite congruent sides are congruent, base angles are congruent, triangle congruence theorems, and CPCTC Color-code all corresponding congruent parts with the same color . Label congruent angles using letters such as xe and y°, etc. Name the two triangles that are congruent State which triangle congruence theorems/corollaries apply. Show work on the figure that verifies...
Without using the Pythagorean theorem, prove that two right triangles are congruent if the hypotenuse and leg of one are equal to the hypotenuse and leg of the other. Do this with placing the triangles so that there equal legs coincide and their right legs are adjacent. This will form a large isoceles triangle. Use this to show that the given triangles are congruent by AAS.

5) Consider the following statements: I: If two triangles are congruent, then they have equal defect. II: If two triangles are similar, then they have equal defect. III: If two triangles have equal defect, then they are similar. IV: If two triangles have equal defect, then they are congruent. Identify which statements can be proved in Neutral Geometry and which cannot be proved in Neutral Geometry. If a statement can be proved, provide a proof. If it cannot be proved,...

A B C Parallelogram ABCD contains two congruent triangles. In two or more complete sentences, use the triangles to prove opposite sides are congruent in parallelogram ABCD
Name Lesson 6 Practice Worksheet Analyze the two congruent triangles. Use à for triangles, for angles, XY for line segments and e for congruence. a. Write a congruence statement for the triangles. b. Identify a sequence of translations, reflections, and/or rotations that could be used to map one triangle onto the other triangle. c. Reverse the order of the transformations that you used in part (b). Does this order map one figure onto the other? d. Can you determine a...
Problem of the Week Problem D Go Fly a Kite Amanda wants to fly a kite. The kite is composed of two isosceles triangles, AABD and ABCD. The height of ABCD is 2 times the height of AABD, and the width of the kite, BD, is 1.5 times the height of the larger triangle. If the area of the kite is 1800 cm, what is the perimeter of the kite? Did you know that in an isosceles triangle the altitude...
