# What is a conjecture about alternate interior angles?

## What is a conjecture about alternate interior angles?

The Alternate Interior Angle Conjecture states: “If two parallel lines are intersected by a transversal, then alternate interior angles are congruent.”

What is an example of corresponding angles?

Corresponding angles are the angles that are formed when two parallel lines are intersected by the transversal. The opening and shutting of a lunchbox, solving a Rubik’s cube, and never-ending parallel railway tracks are a few everyday examples of corresponding angles.

### What is the corresponding angles rule?

The Corresponding Angles Theorem states: If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent. A theorem is a proven statement or an accepted idea that has been shown to be true.

What is an example of conjecture in geometry?

For example, here is a conjecture: When n is a prime number; n + 2 is always prime. 2 + 2 = 4, but 4 is not a prime number. 7 + 2 = 9, but 9 is not a prime number.

#### Which is the corresponding angle to ∠ 1?

120°
Example: Using corresponding angles and straight angles, find the measures of the angles formed by the intersection of parallel lines m and n cut by transversal l below. ∠2 ≅ ∠60° since they are corresponding angles, and m and n are parallel. ∠1 and ∠2 form a straight angle, so∠1=120°.

Is corresponding angles congruent or supplementary?

If the transversal intersects non-parallel lines, the corresponding angles formed are not congruent and are not related in any way. Corresponding angles form are supplementary angles if the transversal perpendicularly intersects two parallel lines.

## How do you write corresponding angles?

Corresponding angles are equal if the transversal line crosses at least two parallel lines….Angles formed when a transversal line cuts across two straight lines are known as corresponding angles.

1. < a and < e.
2. < b and < g.
3. < d and
4. < c and < h.

What are corresponding angles 7?

Definition: Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line (i.e. the transversal). For example, in the below-given figure, angle p and angle w are the corresponding angles.

### Do interior angles add up to 180?

One of the first things we all learned about triangles is that the sum of the interior angles is 180 degrees.

What is conjecture give example?

A statement that might be true (based on some research or reasoning), but is not proven. Like a hypothesis, but not stated in as formal, or testable, way. So a conjecture is like an educated guess. Example: I heard the sound of a plastic bag, so I conjecture there might be some food!

#### What’s a conjecture in geometry?

A conjecture is a mathematical statement that has not yet been rigorously proved. Conjectures arise when one notices a pattern that holds true for many cases. When a conjecture is rigorously proved, it becomes a theorem.

What is the corresponding angle of ∠ 5?

∠5 ≅ ∠120° since ∠1 and ∠5 are corresponding angles, and m and n are parallel. ∠7 and ∠5 form a straight angle, so∠7=60°.

## How do you calculate corresponding angles?

Congruent corresponding angles are: Angle of ‘a’ = Angle of ‘g’ Angle of ‘b’ = Angle of ‘h’ Angel of ‘c’ = Angle of ‘e’ Angle of ‘d’ = Angle of ‘f’. When two straight lines are cut by another line i.e transversal, then the angles in identical corners are said to be Corresponding Angles.

What are some examples of corresponding angles?

When two lines are crossed by another line (called the Transversal): The angles in matching corners are called Corresponding Angles. In this example, these are corresponding angles: a and e. b and f. c and g. d and h.

### What is a corresponding angle?

When two parallel lines are intersected by a third one,the angles that occupy the same relative position at each intersection are called corresponding angles to each other.

• Corresponding angles are congruent to each other.
• If the corresponding angles in the two intersection regions are congruent,then the two lines are said to be parallel.
• What is the definition of corresponding angles?

Definition of corresponding angles. : any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal.
