## Does an acute triangle have perpendicular sides?

Right triangles can come in all sorts of shapes, but they all have that corner, where the right angle sits. You can see that in all the triangles, the right angle has the two sides that are perpendicular to one another. The other two angles are acute angles (meaning they’re less than 90 degrees).

## What angles form perpendicular lines?

Perpendicular lines are lines that intersect at a right (90 degrees) angle.

## How do you know if coordinates are perpendicular?

Explanation: If the slopes of two lines can be calculated, an easy way to determine whether they are perpendicular is to multiply their slopes. If the product of the slopes is , then the lines are perpendicular. In this case, the slope of the line is and the slope of the line is .

## What is the perpendicular Theorem?

The perpendicular axis theorem states that the moment of inertia of a planar lamina (i.e. 2-D body) about an axis perpendicular to the plane of the lamina is equal to the sum of the moments of inertia of the lamina about the two axes at right angles to each other, in its own plane intersecting each other at the point …

## What is the perpendicular transversal theorem?

In a plane, if a line is perpendicular to one of two parallel lines , then it is perpendicular to the other line also. Let the angle between the lines t and k be 1 and that between t and l be 2 .

## Can a transversal line be perpendicular?

Definition: A line that cuts across two or more (usually parallel) lines. It cuts across the parallel lines PQ and RS. If it crosses the parallel lines at right angles it is called a perpendicular transversal.

## What are same side interior angles?

Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

## Is a same side interior angles congruent?

Same side interior angles are on the same side of the transversal. Same side interior angles are congruent when lines are parallel.

## Is same side interior angles the same as consecutive interior angles?

Same Side Interior Angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Converse of the Same Side Interior Angles Theorem: If two lines are cut by a transversal and the consecutive interior angles are supplementary, then the lines are parallel.

## Can the same side interior angles be congruent?

Same side interior angles are sometimes congruent. Rather, they are supplementary (i.e., add up to \$\$180º ), so they are only congruent when they are both \$\$90º .
