## What is a quadrilateral with no parallel?

In India and Britain, they say trapezium ; in America, trapezium usually means a quadrilateral with no parallel sides.) An isosceles trapezoid is a trapezoid whose non-parallel sides are congruent.

## Which quadrilateral is not a parallel parallelogram?

trapezium

A trapezium is the quadrilateral that is not a parallelogram as its two sides are not parallel.

**Can a parallelogram not be a quadrilateral?**

An ordinary quadrilateral with no equal sides is not a parallelogram. A kite has no parallel lines at all. A trapezium and and an isosceles trapezium have one pair of opposite sides parallel.

### How many triangles can a quadrilateral be divided?

The sum of the angles of a quadrilateral is 360º. This can be verified by drawing a diagonal and dividing the quadrilateral into two triangles.

### What do you call a quadrilateral with no parallel sides?

Trapezium. A trapezium (UK: trapezoid) is a quadrilateral with NO parallel sides. The US and UK have their definitions swapped over, like this: Trapezoid. Trapezium. US: a pair of parallel sides. NO parallel sides. UK:

**Is the midsegment of a triangle parallel to the third side?**

The Midsegment Theorem states that the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side. So, if is a midsegment of , then and .

#### Which is the correct definition of the midsegment theorem?

The Midsegment Theorem states that the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side.

#### How are the midpoints of a quadrilateral related?

Form the Triangle Midsegment Theorem, GF||AC and GE||DB, so if m∠EGF=90°, m∠GYZ=90° as it is the supplementary angle of two parallel lines (GE and DB), and also m∠YZX=90°, again as it is the supplementary angle of two parallel lines (GF and AC).
