# What is Cpctc math?

Space and AstronomyCPCTC stands for “**corresponding parts of congruent triangles are congruent**” and tells us if two or more triangles are congruent, then their corresponding angles and sides are congruent as well.

## What is Cpctc and example?

It means that **if two trangles are known to be congruent , then all corresponding angles/sides are also congruent**. As an example, if 2 triangles are congruent by SSS, then we also know that the angles of 2 triangles are congruent.

## What is an example of Cpctc in geometry?

Video quote: *So cpctc it's usually the last part of the reasons column in the two column proof. They basically say that corresponding parts of congruent triangles are congruent. So if these two triangles are*

## What is CSCT in geometry?

CSCT. **Corresponding Sides of Congruent Triangles** (mathematics)

## How do you prove triangles using Cpctc?

Video quote: *So first step is to prove the triangles congruent then everything that matches up or corresponds will be congruent also and that's what the cpctc tells us okay so in this proof.*

## What does Cpctc stand for Quizizz?

What does CPCTC stand for? **Congruent parts of congruent triangles are congruent**.

## What angles are congruent to 6?

Answer: **∠8** is congruent to ∠6 because they are vertical angles, or opposite angles.

## How do you construct a plane in geometry?

Video quote: *Which is called a plane think of a plane as a wall or the floor of a room a flat surface that has no thickness to represent the idea of a plane. We can use a four-sided.*

## What is angle 4 and angle 6 called?

angle 4 and angle 6 adjoining figure is known as **co interior angles**.

## What is the name of the relationship between ∠ 1 and ∠ 8?

Angles that are on the opposite sides of the transversal are called **alternate angles** e.g. 1 + 8. All angles that are either exterior angles, interior angles, alternate angles or corresponding angles are all congruent.

## What is the relationship between angle 3 and 6?

Corresponding angles are at the same location on points of intersection. Next we have alternate interior angles. Located between the two intersected lines, these angles are on opposite sides of the transversal. Angles 2 and 7 above, as well as angles 3 and 6 are examples of **alternate interior angles**.

## What is the relationship of 1and 2?

Angles 1 and 2 are **adjacent angles** because they share a common side.

## What is the relationship between angle 2 and 3?

They are equals if the two intersected lines by the transversal are parallel. In the figure, angles 2 and 3 are **alternate interior angles**.

## What is the relationship between angle 2 and angle 8?

Video quote: *So these two must also add up to 180 lastly angles in the same position with respect to one another are called corresponding angles we will see diagrams like this quite a lot in geometry.*

## What is the relationship between angle 1 and angle 5?

∠1 and ∠5 are **corresponding angles**, so they have equal measures.

## How do you solve an angle relationship?

Video quote: *If I know that Y is 40 degrees well x and y are complementary. So I could set that up to say X plus angle Y is 90. I could subtract 40 and show my work to get the measurement of angle X is 50 degrees.*

## How do you find angles in math?

The formula for finding the total measure of all interior angles in a polygon is: **(n – 2) x 180**. In this case, n is the number of sides the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.

## How do you do algebra with angles?

Video quote: *We get 180 degrees that's the sum of the angles of a triangle. So we can use our algebra. And say well X plus the quantity X minus 3 plus the quantity 5x plus 8 will give us 180.*

## How do you find the angle of an equation?

Video quote: *All straight angles are 180 degrees. So the two angles together would be supplementary angles. So we know in the problem that both of the angles added together must equal 180 degrees.*

## How do you find the angle in a circle?

Video quote: *So if the arc intercepted arc is 135. Then that angle must also be a hundred and thirty-five.*
