Video transcript There is a half an apple pie left. So it’s going to be equal to degrees. What type of quadrilateral is each figure? Draw the point that is the center of rotation. Tell what is the same and what is different about the original figure and its image. Draw the line of reflection. Now, to solve for x, we can subtract 30 degrees from both sides.

But we only have half a pie here. What is the measure of your piece of the pie in degrees? Underline two parts that you think make it a particularly good answer and a helpful example. The lengths of the sides are the same, and the measures of the angles are the same. Summative — Geometry Grade 3 Summative for geometry Grade 3.

And just to visualize it over here, let me draw it down here where it’s easier to see it. The image is in a different location than the original figure.

Study the example problem showing how to compare the properties of two shapes. Find measure of angles word problem. Then solve problems 1—6. The figures have the same shape and size.

Now, to solve for x, we can subtract 30 degrees from both sides.

# Understand Properties of Transformations

Lesson 18 Understand Properties of Transformations Name: Compare the properties of the figures. So I have 3x plus 30 degrees is going to be equal to, of course, degrees.

We only have degrees of pie left, but let’s just keep that in mind and think about how we’re going to split it between ourselves, our brother, and our mom. Label this figure B.

## Find measure of angles word problem

Let’s let x be equal to the degree measure of my brother’s pie or your little brother’s pie. You want to eat twice what your little brother eats, but you also need to save a slice for your mom.

If you’re seeing this message, it means we’re having trouble loading external resources on our website. The transformation is a translation. Math 7th grade Geometry Missing angle problems. Draw any lines of reflection or centers of rotation on the grid.

Explain how you got your answers. So that’s 30 degrees for your mom. Compare the properties of the figures. So the amount that your brother eats, x, plus the amount that you eat, plus the amount that your mom gets, plus 30 degrees, is going to be equal to this half pie.

So what is the measure of your piece of the pie in degrees?

How was the green figure transformed to get image A? Video transcript There is a half an apple pie left. So let’s define some variables.

Imani says it is a reflection. Then solve problems 1—6. Transformations in the Coordinate Plane.

And now we can just divide both sides by 3, and we’re left with x equaling divided by 3 is 50 degrees. Find the rest of the angle measures in each triangle and compare them. After the figure is transformed: Example The gray figure is a transformation of the green figure.
