Are two isosceles right triangles always similar?
No
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
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.
Is a scalene always isosceles?
No. A scalene triangle is never isosceles. An isosceles triangle has two equal sides. A scalene triangle has none.
What is the ratio of Two similar trapezoids that have areas of 49cm2 and 9 cm2 find their similarity ratio?
7:3
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 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.
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
Are Two isosceles triangles are sometimes always or never similar to each other?
Sometimes.
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.
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.
Are two isosceles triangles similar?
Yes, as long as they're both isosceles
