Are two isosceles right triangles always similar?
No
Can a cut be made between two parallel sides of an isosceles trapezoid to make two isosceles trapezoids?
No, a cut cannot be made between two parallel sides of an isosceles trapezoid to create two isosceles trapezoids. An isosceles trapezoid has only one pair of parallel sides, so cutting between them would result in two separate shapes, neither of which would be an isosceles trapezoid. The resulting shapes would likely be irregular quadrilaterals or triangles, depending on the location of the cut.
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
Do all isosceles trapezoids have reflectional symmetry?
Yes, all isosceles trapezoids have reflectional symmetry. This symmetry occurs along a vertical line that bisects the shape, passing through the midpoints of the two bases. The two non-parallel sides are equal in length, ensuring that one half mirrors the other across this line of symmetry. Thus, an isosceles trapezoid can be folded along this line, and the two halves will match perfectly.
Is a scalene always isosceles?
No. A scalene triangle is never isosceles. An isosceles triangle has two equal sides. A scalene triangle has none.
Do trapezoids have two pairs of congruent sides?
Only when they are isosceles trapezoids.
Are two isosceles triangle always similar?
no
Are two isosceles right triangles always similar?
No
Does the median of an isosceles trapezoid create two isosceles trapezoids?
A trapezoid does not have a median since from any vertex, there is no single opposite side.
Are all trapezoids scalene?
No, not all trapezoids are scalene. A trapezoid is defined as a quadrilateral with at least one pair of parallel sides, and it can have varying side lengths and angles. Some trapezoids can have two sides of equal length, making them isosceles trapezoids, while others can have all sides of different lengths, classifying them as scalene. Thus, trapezoids can be either scalene or isosceles.
Are an isosceles and a scalene triangle always similar?
No. An isosceles has two equal sides and two equal angles. A scalene has no equal sides and no equal angles.
Can a cut be made between two parallel sides of an isosceles trapezoid to make two isosceles trapezoids?
No, a cut cannot be made between two parallel sides of an isosceles trapezoid to create two isosceles trapezoids. An isosceles trapezoid has only one pair of parallel sides, so cutting between them would result in two separate shapes, neither of which would be an isosceles trapezoid.

Are Two isosceles triangles are sometimes always or never similar to each other?
Sometimes.
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
Are parallelograms and trapezoids always similar?
yes * * * * * Never. A parallelogram has two pairs of equal angles opposite one another. A trapezoid does not.
Find the area of the rectilinear if it is the difference between two isosceles trapezoids whose corresponding sides are parallel?
51.132 sq. in
How many congruent angles does an isosceles trapezoid have?
By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
