# What is A and B in a trapezoid?

## What is A and B in a trapezoid?

A trapezoid is a four sided (polygon) quadrilateral in which one pair of opposite sides are parallel. The area of a trapezoid is the number of unit squares that can fit into it. It is mathematically expressed as A = ½ (a + b) h, where ‘a’ and ‘b’ are the bases (parallel sides) and ‘h’ is the perpendicular height.

## What is the formula for b1 in a trapezoid?

The area of a trapezoid is A= (1/2) h (b1 + b2) , where h=height of the trapezoid, b1= 1st base, and b2= second base.

What are the 3 types of trapezoid?

Trapezoids are of three kinds – Isosceles, Scalene, and Right. In the case of the isosceles trapezoid, the diagonals are equal since the non-parallel or the legs of the trapezoid are equal in length.

### What is a trapezoid an example of?

Trapezoids are quadrilaterals with one set of parallel sides. If the quadrilateral has two sets of parallel sides it is a parallelogram. Some mathematicians define trapezoids as quadrilaterals with at least one set of parallel sides, then a parallelogram is also a trapezoid.

### Does a trapezoid have equal sides?

A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.

Can a trapezoid have 1 right angle?

Explanation: A trapezoid can have either 2 right angles, or no right angles at all.

## What is a trapezoid in real life?

A trapezium is four sided shape with two parallel sides, one longer than the other, and two lines that connect those two sides. Few examples of trapeziums in real life are roofs of houses, table tops, windows and doors, pencil boxes etc. A trapezoid is a quadrilateral with one pair of opposite sides parallel.

## How to find the base of a trapezoid?

How to find a base of a trapezoid give the one of the bases, the height, and the area. The main area formula above has four variables (area, two bases and height). If we know any three we can always find the fourth.

Where is the trapezoid in the Baltimore area?

— Sarah Boyd, Forbes, 15 Apr. 2021 The neighborhood is a trapezoid bounded by East 33rd Street, Greenmount Avenue, Loch Raven Road and East 25th Street. — Sameer Rao, baltimoresun.com, 31 Mar. 2021 So, what’s that plastic trapezoid perched atop the steering column of the 2021 Ford Mustang Mach-E?

### How to calculate Bf / CF for a trapezoid?

Theorem Given a trapezoid ABCD with parallel sides AB and CD, with E the point of intersection of the diagonals AC and BD. If e is the line through E parallel to AB, then if e intersects BC in F and DA in G, the ratios BF/CF = AG/DG = AB/CD. Theorem Given a trapezoid ABCD with parallel sides AB and CD.

### Which is an isosceles trapezoid AB or CD?

Isosceles Trapezoids A trapezoid ABCD with parallel sides AB and CD is called an isosceles trapezoidif it is a strict trapezoid with BC = DA. Notice that if ABCD is a parallelogram, it is a (non-strict) trapezoid with BC = DA.
