180 degrees
The base angles of an isosceles trapezoid are congruent
A trapezoid may have no right angles, or it may have two adjacent ones.
If the height of the trapezoid is 9 and the base is 26, then it appears likely to us that the base is 26.
The perimeter of a trapezoid is the sum of its bases and legs. The area of a trapezoid is the height times (base 1 + base 2) divided by 2
None. A trapezoid has 4 angles, but not 4 angels.
A trapezoid is a quadrilateral and has four faces.
No.
180 degrees
If the trapezoid is an isosceles trapezoid, with congruent legs, then the base angles are congruent. Otherwise, no.
The base angles of an isosceles trapezoid are congruent
A trapezoid.
A trapezoid may have no right angles, or it may have two adjacent ones.
isosceles trapezoid
3D trapezoid
Only if it is an isosceles trapezoid which has one line of symmetry.
If the height of the trapezoid is 9 and the base is 26, then it appears likely to us that the base is 26.
