Base angles are equal

To prove a trapezoid is isosceles, you need to show that the legs (the non-parallel sides) are congruent. This can be done by demonstrating that the base angles opposite these sides are congruent. You can use the triangle congruence postulates or the properties of parallel lines and transversals to establish the equality of these angles.

Are diagonals of an isoceles trapezoid congruent?
Yes
How many congruent sides do isoceles trapezoid?
At least 2. (If all 3 sides are congruent it's equallateral, but can still be called isoceles)
What makes an isoceles trapezoid special?
The type of characteristics a trapezoid has or any other shape has makes it special in so many different ways
What does an Isociles trapezoid look like?
It looks like an isoceles triangle that has had its vertex cut off parallel to its base.
How do you make a triangle out of 3 trapezoids?
There is no combination of trapezoids which can form a triangle. well not exactly, if you have three " isoceles like trapezoid", then you can, provided, you are allowed to overlap. you should be able to figure it out now.... What if the triangle was equilateral and the trapezoids were isoceles? You wouldn't need the trapezoids to overlap. Use the longer 'bottom' edge of each trapezoid and the 'left' edge of the next trapezoid to make up the edge of the triangle. The shorter 'top' edge of the trapezoids touch the 'right' edge of the next trapezoid in the center of the triangle.
Are diagonals of an isoceles trapezoid congruent?
Yes
Are the base angles of an isosceles trapezoid congruent?
Yes they are. Basically you can think of an isoceles trapezoid as an isoceles triangle with the top cut off parallel with the base.
How many congruent sides do isoceles trapezoid?
At least 2. (If all 3 sides are congruent it's equallateral, but can still be called isoceles)
What makes an isoceles trapezoid special?
The type of characteristics a trapezoid has or any other shape has makes it special in so many different ways
What degrees does an isoceles trapezoid measure?
The 4 interior angles add up to 360 degrees
What are six shapes that have four sides?
All of these are varieties of quadrilaterals. Some include: squares rectangles rhombus (diamond) trapezoid parallelogram kite isoceles trapezoid
Is an isoceles trapezoid a quadrilateral?
yep bcuz it has 4 sides which makes it a quadrilateral

What is a isoceles trapezoid?
It is a quadrilateral that has 2 parallel sides of different lengths and 2 sides of equal length with base angles being equal
How do you prove quadrilateral is a trapezoid?
You can't. A trapezoid is a quadrilateral because it has four sides. The definition of a quadrilateral is a shape with four sides.
How do you prove that a trapezoid is isosceles?
You prove that the two sides (not the bases) are equal in length. Or that the base angles are equal measure.
