You can use the Converse of the Triangle Proportionality Theorem to verify that a line is parallel to a side of a triangle. Example41 Verify that the line segments are p 21 M 20 cm E 15 cm 8. MN and KL JM 42 MK — 21 JN 30 , MN KL by the Converse Of the Since MK NL Triangle Proportionality Theorem. DE and AB (Given that AC = 36 cm, and BC = 27 cm Similar triangles are triangles with the same shape but different side measurements. Learn how to prove triangles similar with these theorems. they would be similar. An equilateral triangle with sides 21 cm and a square with sides 14 cm would not be similar because they are different shapes. 20 40 = 1 2. 25 50. One polyhedron has surface area 4,400 cm^2 and volume 16,000 cm^3. Give the surface area and the volume of the polyhedron's image for a dilation with scale factor 3/4. The side length of square. The perimeter is 36 \ cm and the area is 54 \ cm^2. In a right triangle, the longest side is always the hypotenuse. How do you find the perimeter and area of a right triangle if the shortest side is 9cm and the longest side is 15cm? Algebra Expressions, Equations, and Functions Problem-Solving Models. 1 Answe
