Answer:
Statement 1, 3 and 5 statements are true.
Step-by-step explanation:
Given the following statements we have choose the statements which are true for trapezoid.
Statement 1 : It is a quadrilateral
Any 4 sides polygon is quadrilateral. Trapezoid also have 4 sides
Hence, trapezoid is quadrilateral.
Statement 2: It has two right angles
Only the right trapezoid has 2 right angles.
Hence, not true for every trapezoid.
Statement 3: It has only one pair of parallel sides.
A quadrilateral with one pair of parallel sides is trapezoid. If it has two pairs of parallel sides then it is a parallelogram
Hence, true statement.
Statement 4: Any sides can be the base
The parallel sides are called the bases and the other two sides are called the legs of trapezoid.
Hence, not true.
Statement 5: The end points of the altitude are on each base.
Altitude are always perpendicular and the parallel sides are called the bases. This implies the end points of the altitude are on each base.
Hence, true statement.
