# What are parallel sides of a triangle?

## What are parallel sides of a triangle?

A midsegment is parallel to one side of a triangle and divides the other two sides into congruent halves. The midsegment divides those two sides proportionally….Investigation: Triangle Proportionality.

## Can any 2 side of a triangle be parallel?

Answer. No, we cannot say that the two sides of a triangle are parallel.

## How do you find a parallel triangle?

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally. If ¯DE∥¯BC , then ADDB=AEEC .

## How do you know if triangles are parallel?

If a line intersects two sides of a triangle and splits those sides in equal proportions, then that line must be parallel to the third side of the triangle.

## How many lines does a triangle have?

A triangle is composed of three line segments. The line segments intersect in their endpoints. To name a triangle we often use its vertices (the name of the endpoints). The triangle below is named ABC.

## Why can’t a triangle have parallel sides?

None. Parallel lines are lines that will never cross each other, no matter how long you make them. A triangle is a polygon that has three sides and… See full answer below.

## Does an acute triangle have parallel sides?

Any triangle in which the Euler line is parallel to one side is an acute triangle. Acute triangles can be isosceles, equilateral, or scalene.

## How many parallel sides can a rectangle have?

2 pairs Answer: A rectangle has 2 pairs of parallel sides. In a rectangle, the two lines forming a pair of parallel sides are also congruent, unlike a parallelogram. Explanation: Just like a square, a rectangle has 4 sides at right angles forming 2 pairs of parallel sides.

## Are parallel sides of a triangles congruent?

2. If there are corresponding angles between parallel lines, they are congruent. 3. If there are congruent triangles, all their angles are congruent.

## Are parallel sides?

Lesson Summary Parallel sides are a unique property of certain shapes. These are sides that will never meet and are always the same distance apart. Some shapes that have parallel sides include the parallelogram, the rectangle, the square, the trapezoid, the hexagon, and the octagon.

## How many sides can a triangle have?

three sides Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs. All triangles are convex and bicentric.

## What shape has 2 pairs of parallel sides?

What is a parallelogram? A parallelogram is a quadrilateral with 2 pairs of parallel sides. In these figures, sides of the same color are parallel to each other.

## Are parallel sides equal?

A parallelogram is a two-dimensional shape. It has four sides, in which two pairs of sides are parallel. Also, the parallel sides are equal in length.

## How many parallel sides does a rectangle have?

two sets What is a rectangle? A rectangle is a quadrilateral with 4 right angles. A shape with four sides of equal length. The shape has two sets of parallel sides and has four right angles.
