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?
Yes. Any cut parallel to the base will do.
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
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
Can a cut be made between two parallel sides of an isosceles trapezoid to make two isosceles trapezoids?
Yes. Any cut parallel to the base will do.
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.
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.
How are isosceles trapezoids related to parallelograms?
They are convex quadrilateralsboth have at least one pair of parallel lines.both have two pairs of equal angles.
