They also preview finding all unknown values in right triangles, which is a key idea in a subsequent unit. Students have a chance to reason abstractly and quantitatively as they think about whether their answers make sense in context (MP2).Geo.2 Congruence. In this unit, students begin by reasoning about the relationships between congruent parts of figures, and congruent figures. They use transformations as tools for reasoning and generalizing. Students use transformations to prove three theorems about triangle congruence: Side-Angle-Side Triangle Congruence, Angle-Side-Angle ...Arrange students with a partner who prefers the same method. Display a pair of triangles where one has sides twice as long as the other, and all the pairs of corresponding angles are congruent. Give students 1 minute to talk with their partner about their strategy for lining up the triangles.

For each question, Event A is "game played when warmed up" and Event B is "more shots made than missed.". Use the data to estimate the probabilities. Use and to determine if the two events are dependent or independent. Show or explain your reasoning.Geo.3 Similarity. In this unit, students use dilations and rigid transformations to justify triangle similarity theorems including the Angle-Angle Triangle Similarity Theorem. Students explicitly build on their work with congruence and rigid motions, establishing that triangles are similar by dilating them strategically.The goal of the discussion is to reinforce the idea that when a figure is dilated by a factor of , its area changes by a factor of . Draw any non-rectangular shape and display it for all to see. Tell students the shape has an area of 40 square units. Ask students: "Suppose we dilate this shape by a factor of 2.In this lesson, students learned that the slope of a line can be a negative value or 0. They saw some linear relationships with a negative slope and some with 0 slope. Students learned about cues to identify whether a graphed line has a positive slope, a negative slope, or 0 slope. Display the graph for all to see.Things students may notice: The first quadrilateral has 4 90 degree angles. It fits the idea that cyclic quadrilaterals have supplementary pairs of opposite angles. The third quadrilateral does not have supplementary pairs of opposite angles. One pair of opposite angles are both obtuse and the other pair are acute.This warm-up prompts students to compare four expressions. It gives students a reason to use language precisely (MP6). It gives the teacher an opportunity to hear how students use terminology and talk about characteristics of the items in comparison to one another. Launch. Arrange students in groups of 2–4. Display the expressions for all to ...Problem 4. The dot plot shows the weight, in grams, of several different rocks. Select all the terms that describe the shape of the distribution. A: bell-shaped. B: bimodal. C: skewed.Advertisement People have been building domes for centuries. Ancient peoples such as the Romans applied their masonry skills -- and their knowledge of the arch -- to create massive...Geo.4 Right Triangle Trigonometry. In this unit students build an understanding of ratios in right triangles which leads to naming cosine, sine, and tangent as trigonometric ratios. Practicing without naming the ratios allows students to connect similarity, proportional reasoning, and scale factors to right triangles with a congruent acute ...Enjoy these free sheets.

They see each input-output pair of a function as a point with coordinates when is the input, and use information in function notation to sketch a possible graph of a function. Students' work with graphs is expected to be informal here. In a later lesson, students will focus on identifying features of graphs more formally.The purpose of this Math Talk is to elicit strategies and understandings students have for using the triangle congruence theorems (in particular, Angle-Side-Angle) as part of proving that triangles are similar. These understandings will be helpful later in this lesson when students will need to be able to use the Angle-Side-Angle Triangle ...The activity allows students to practice solving systems of linear equations by substitution and reinforces the idea that there are multiple ways to perform substitution. Students are directed to find the solutions without graphing. Monitor for the different ways that students use substitutions to solve the systems.
