Question

properties of isosceles trapezoid​__________



5Tnx Please ❤️​

Answer 1

The properties of the isosceles trapezoid are as follows:

• The properties of trapezoid apply by definition (parallel bases).
• The legs are congruent by definition.
• The lower base angles are congruent.
• The upper base angles are congruent.
• Any lower base angle is supplementary to any upper base angle.

Answer 2

Answer:

Property 1: Only one pair of sides are parallel. AB ∥ CD

Property 2: Non-parallel sides (legs) are equal in measure. AD = BC

Property 3: The diagonals are equal in measure. AC = BD

Property 4: The base angles are equal in measure. ∠D = ∠C

Property 5: The opposite angles are supplementary. ∠D +∠B = 1800 and ∠C +∠A = 1800

Property 6: The segment which joins the midpoints of the parallel sides is perpendicular to them.

Property 7: An isosceles trapezium can be inscribed in a circle.Property .

8: The diagonals form a pair of congruent triangles with equal sides as the base and the other pair – similar triangles.
