They are congruent angles.
No but it has congruent base angles. Also it has: One pair of parallel sides Non-parallel sides that are equal Two pairs of equal angles Diagonals that are equal
C. Congruent Bases
Yes but the parallel bases are of different lengths
An isosceles trapezoid has a pair of parallel bases and a pair of congruent sides
You prove that the two sides (not the bases) are equal in length. Or that the base angles are equal measure.
False.
No but it has congruent base angles. Also it has: One pair of parallel sides Non-parallel sides that are equal Two pairs of equal angles Diagonals that are equal
No. The other two sides are congruent.
False.
C. Congruent Bases
Its base angles are the same and it has a pair of opposite parallel sides of different lengths with one line of symmetry.
Yes but the parallel bases are of different lengths
An isosceles trapezoid has a pair of parallel bases and a pair of congruent sides
An isosceles trapezoid is a quadrilateral that has parallel bases of different lengths, two equal sides and the lateral base angles are equal. Interior angles add up to 360 degrees Exterior angles add up to 360 degrees
You prove that the two sides (not the bases) are equal in length. Or that the base angles are equal measure.
parallel
Since a trapezoid is a quadrilateral whose bases are parallel and not congruent, then one of its sides can be perpendicular to its bases (as the shortest distance between two parallel lines). Such a trapezoid is called a right trapezoid.
