Isosceles triangles have two equal sides.
The angles opposite the equal sides are also equal.
For instance, if the top angle is 48o and the two bottom angles are 66o an acute isosceles triangle is formed.

If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
How many angles does a isosceles have?
An isoceles is a type of triangle with two sides of equal length. Like all triangles an isoceles triangle has three interior angles.
Does an Isosceles have two equal sides?
Yes. Isosceles triangles have two identical sides and angles. They are also longer than the third side.All triangles have three sides. Isosceles triangles have two sides of the same length.
How many right angles does a isosceles triangle have?
It can only have a maximum of one- and that is only if it is a right-angled isosceles triangle. ----------------------------------------------------- Yes not all isosceles triangles are right angle triangles - this is a special case.
Are diagonals in isosceles triangles congruent?
yea an isosceles has perfect angles 45-45-90, thus meaning congruent.
Which type of triangles has exactly two sides that are congruent?
An Isosceles triangle has two sides (and two angles) congruent.
Are angles in an isoceles triangle equal?
Isosceles triangles have at least 2 equal angles. The 3rd angle can either be equal to the other two (it's then called an equilateral triangle), or it can be different from the two equal angles, in which case it's an isosceles triangle. All equilateral triangles are isosceles triangles, but not all isosceles triangles are equilateral triangles.
An isosceles triangles has how many angles?
3
Are all right triangles an isosceles triangles?
Yes- but not all isosceles triangles are right triangles. Isosceles means that two sides are the same length, and two angles are the same.
A type of triangle with no equal sides?
There are three types of triangles. Scalene triangles have no congruent sides or angles, equilateral triangles have 3 congruent sides and 3 60degree angles, and isosceles triangles have two congruent sides and two congruent angles.
What are two isosceles triangles with congruent vertex angles?
They're similar triangles.
What are the properties of isosceles triangles and an equilateral?

Is it true that isosceles triangles have to have acute angles?
Yes
If the vertex angles of two isosceles triangles are congruent are the triangles always similar?
Yes, they are.
What is the relationship between isosceles and acute triangles?
They are both triangles. And both have acute angles
What does Isosceles Triangle and Equilateral Triangle have that is different?
Equilateral triangles have 3 equal sides, but isosceles only have two equal sides. Also, equilateral triangles have three 60° angles. Isosceles triangles have two congruent base angles and a vertex angle.
What angles are in an isosceles triangle?
well, it depends on the triangles size
