Identify Pairs Of Angles - Framework
CENTER ACTIVITYName:LESSON 6Identify Pairs of AnglesWhat You Need Label Cards Figure CardsWhat You Do1Place the “congruent” and “supplementary” Label Cards side by side on one sideof the table. Place the Label Cards faceup on the other side of the table. Shufflethe Figure Cards and place them in a pile facedown.2Take turns. Draw a Figure Card. Then find a Label Card that describes thenumbered angles.3Explain how the measures of the numbered angles are related, if at all. If you have enough information to know whether the angles are congruentor supplementary, place the Figure Card with its Label Card under either“congruent” or “supplementary.” If you do not have enough information, discard the cards.4Continue until no cards are left.Check UnderstandingIn the figure, m/1 5 110 .

CENTER ACTIVITYNames:LESSON 27Find Pythagorean TriplesWhat You Need Score Card, 1 per player Game Board number cube (1–6) counters, 1 of a different color per playerWhat You Do1Give each player a Score Card. Each row of the card shows theleg lengths of a Pythagorean triple.KEEP IN MIND . . .You can use the factthat a multiple of aPythagorean triple isalso a Pythagorean triple.For example, 10, 24,is a multiple of 5, 12, .2Take turns. On your turn, roll the number cube. If possible, writethe number rolled in one of the blank spaces on your ScoreCard. Each number you write will be either the ones digit or tens digit of thehypotenuse length for one Pythagorean triple. If there are no blank spaces forthe number rolled, your turn is over.3When you complete your first Pythagorean triple, have the other players checkyour work. If you are correct, place your counter on home plate on the GameBoard. If you are not correct, your turn ends. Each time you complete anothertriple, move to the next base.4The first player to get back to home plate wins.Check UnderstandingWhich set of numbers is a Pythagorean triple?

Identify a pair of corresponding angles, a pair of same-side exterior angles, and a pair of alternate interior angles. What are the measures of the angles in each pair? Explain how you know. Go Further Choose a Figure Card and estimate the measure of one of the numbered angles. Use your estimate to calculate the measure of the other numbered angle.
Adjacent angles are two angles that share a common vertex and side, but have no common interior points. 5 and 6 are adjacent angles 7 and 8 are nonadjacent angles. Notes: Linear Pairs and Vertical Angles Two adjacent angles are a linear pair when Two angles are vertical angles when their noncommon sides are opposite rays.
