Introduction to proofs: Identifying geometry theorems and postulates ANSWERS C congruent ? Explain using geometry concepts and theorems: 1) Why is the triangle isosceles? PR and PQ are radii of the circle. Therefore, they have the same length. A triangle with 2 sides of the same length is isosceles. 2) Why is an altitude? AB = AB (reflexive ...

Each side of square B is 9 cm. What is the ratio of the perimeters of A to B? Perimeter ratio is identical to sides ratio. perimeter of A: 24 24:36 or perimeter of B: 36 or What is the ratio of the areas of the 'squares'? Area ratio is ratio of the "squares" or area of A: 36 areaofB: 81 62: 9 36:81
Similar triangles: Side - Angle - Side Definition: If a pair of coresponding sides of 2 triangles have the same ratio AND the included angles are congruent, then the triangles are similar. A DEF ratio of 2 sides are equal, & non-included angles are congruent but, triangles are not similar! Comments: Example: A ABC
Law of Cosines What is it? Equations that relate the interior angles of a triangle to their coresponding (opposite) sides. In a triangle, "two known sides and the included angle can determine the length ofthe 3rd side' Law of Cosines a b Examples: — 2bc(cosA) — 2ac(cosB) — 2ab(cosC) 1) Given the following triangle, find the length of d.

3. Provide each student with a card that contains the description of one of the quadrilaterals studied. 4. Each student must use the items in the bag to construct the quadrilateral on his or her card, making it identifiable to others in his or her group. 5. Using their definitions, students must justify the construction of the figures (NCTM, 2000).
quadrilaterals, but may not be a ble to distinguish between a rhombus and a parallelo gr am. Q. I’ve seen other numbering schemes for the le vels. Wh y? A . In their original works, the van Hieles numbered the le vels from 0 to 4. Americans started numbering the le vels from 1 to 5 instead .T his scheme
