For each pair of points, find the slope of the line that passes through both points. Problem 3 Draw two polygons that are not similar but could be mistaken for being similar. Are the two triangles similar? Measure the longest side of each of the three triangles. You can use the free Mathway calculator and problem solver below to practice Algebra or other math topics. Problem 4 These two triangles are similar. Problem 3 The two triangles shown are similar.

Problem 3 Here is a triangle. Clare says the two triangles are congruent, because their angle measures are the same. O is the center of dilation and the scale factor is 1. A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. For each pair, describe a point and a scale factor to use for a dilation moving the larger triangle to the smaller one. Rotate to landscape screen format on a mobile phone or small tablet to use the Mathway widget, a free math problem solver that answers your questions with step-by-step explanations.

Plot the points for each dilation described.

# Dilate triangles (practice) | Dilations | Khan Academy

Problem 2 Here are two similar polygons. For each pair, describe a point and a scale factor to use for a dilation moving the larger triangle to the smaller one. For each pair of points, find the slope of the line that passes through both points. Dilationa is then called a reduction. Elena uses Triangle B and says no, the slope of this line is 1. Do you agree with either of them? Label any new points.

What are some ways you can convince Jada that her claim is not true? Problem 4 from Unit 1, Lesson 15 Which of these sets of angle measures could be the three angles in a triangle?

Problem 1 For each pair of points, find the slope of the line that passes through both points. If the scale factor of a dilation is between 0 and 1, the image will be smaller than the object.

## Dilation Transformation

Are the two triangles similar? If you get stuck, try plotting the points on graph paper and drawing the line through them with a ruler. Draw an image of the figure PQRS. The straight line is drawn from a fixed point called the center of dilation.

Dilation is a transformation in which each point of an object is moved along a straight line. Problem 3 Consider the graphed line. Problem 4 from Unit 2, Lesson 7 A rectangle has length 6 and height 4.

Measure the side lengths and angles of each polygon. Note that in this example, all the points in the triangle have been transformed except point C, which is the only invariant point. Dilationw Geometry Lessons Transformation Games In these lessons, we will learn what is dilation or enlargement and reduction? Problem 3 Here are three polygons.

## Unit 2: Practice Problem Sets

Try the given examples, or type in your own problem and check your answer with the step-by-step explanations. Measure the side lengths and angles of your triangles. If the scale factor is between 0 and 1, the image is a reduction. Select all that apply.

Use a measurement tool to find the scale factor. The center of dilation is the only 5-66 point. Find the measures of the following angles. Do you think two equilateral triangles will be similar alwayssometimesor never? Problem 3 Here is a triangle. A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

What are the measures of the other two angles? These two triangles are similar.
