You prove that the two sides (not the bases) are equal in length. Or that the base angles are equal measure.
Yes, an isosceles trapezoid is symmetrical.
If you extend the two legs of an isosceles trapezoid until they intersect, you get an isosceles triangle.
No. It can be but need not be.
The base angles of an isosceles trapezoid are congruent
yes! But only an isosceles Trapezoid.
Measure them
No, not every trapezoid is an isosceles trapezoid.
An isosceles trapezoid
Yes, an isosceles trapezoid is symmetrical.
how is an isoscelels trapezoid related to a isosceles triangle
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
The diagonals of an isosceles trapezoid are equal in lengths
what is isosceles
If you extend the two legs of an isosceles trapezoid until they intersect, you get an isosceles triangle.
No. It can be but need not be.
If the two sides which are not parallel have equal lengths, then the trapezoid is called an isosceles trapezoid (standard trapezoid has unequal sides). The base angles in an isosceles trapezoid are equal in measurement, also I know that a trapezoid with two nonparallel sides the same length is called an isosceles trapezoid.
A ISOSCELES TRAPEZOID HAS ONE LINE OF SYMMETRY.....
