Step: 1

A trapezoid is a quadrilateral that has exactly one pair of parallel sides.

Step: 2

From the figures, figure C is a quadrilateral and has exactly one pair of parallel sides.

Step: 3

Figure C represents a trapezoid.

Correct Answer is : Figure C

Step: 1

A triangle in which all the three sides are equal and all angles are equal is called an equilateral triangle.

Correct Answer is : an equilateral

Step: 1

A parallelogram is a quadrilateral in which, the pair of opposite sides are parallel and opposite angles are equal.

Step: 2

All the figures given in the choices A, B, and C are parallelograms.

[The opposite sides and angles are equal in all figures.]

Correct Answer is : All the above

Step: 1

An equilateral triangle is a triangle in which all the three sides and the angles are congruent.

Step: 2

So, the statement, 'An equilateral triangle has three angles equal', is true.

Correct Answer is : An equilateral triangle has three angles equal.

Step: 1

Among the choices given, a triangle has 3 sides, a square and a rectangle have 4 sides each, and a pentagon has 5 sides.

Step: 2

5 > 4 > 3

Step: 3

So, Greg can draw a pentagon.

Correct Answer is : pentagon

Step: 1

A quadrilateral with two pairs of opposite sides parallel is called a parallelogram.

Step: 2

So, among the choices, 2 pairs of parallel lines best describes the parallelogram.

Correct Answer is : 2 pairs of parallel lines

Step: 1

The lengths of the three sides of a triangle are same, and equal to 7 in.

Step: 2

So, the triangle is an equilateral triangle.

Correct Answer is : equilateral triangle
