What is is an isosceles triangle?
An isosceles triangle is any triangle with at least two sides of equal length. Logically, an isosceles triangle also has at least two angles of equal size. An equilateral triangle is a triangle with three equal sides and three equal angles (all of which are 60 degrees). Since it has at least two equal sides then it is therefore also an isosceles triangle. This is no different to the way in which a square is also a rectangle, or a circle is also an ellipse. They are simply special cases of the general case.
How many degrees in an isosceles tringle?
All triangles have a total of 180 degrees. In an isosceles triangle the two angles opposite the side of equal length will have equal degrees.
What is right angle triangle and isoceles triangle?
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.
Which is a triangle with two sides the same length and an interior angle measuring 100 degrees?
It is an isosceles triangle and the other 2 angles will each measure 40 degrees
Can an obstuse triangle also be isosceles?
No, an obtuse triangle cannot be isosceles. An isosceles triangle has two sides that are equal in length, but in an obtuse triangle, the angles are all greater than 90 degrees. Therefore, the sides cannot be equal in length.
What kind of triangle has angles 50 degrees 65 degrees and 65 degess?
Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides/ angles.

What is right angle triangle and isoceles triangle?
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.
How much degrees are in a isoscelese triangle?
The angles inside any triangle sum to 180 degrees. Isosceles simply means two sides are the same length.
How many degrees should there be in an isosceles triangle?
In the equilateral triangle, all the sides are the same length and all the angles are the same size (congruent). Since the sum of the angles of a triangle is always 180 degrees, we can figure out the measure of the angles of an equilateral triangle.Another Answer:-An isosceles triangle has 2 equal base angles plus another angle and the 3 interior angles add up to 180 degrees.
What ia a isosceles triangle?
An isosceles triangle has 3 sides 2 of which are equal in length and 3 interior angles that add up to 180 degrees 2 of which are equal in size

Can an obstuse triangle also be isosceles?
No, an obtuse triangle cannot be isosceles. An isosceles triangle has two sides that are equal in length, but in an obtuse triangle, the angles are all greater than 90 degrees. Therefore, the sides cannot be equal in length.
What are the rules for an isosceles triangle?
An isosceles triangle has two sides that are equal in length and thus two equal angles.
How do we determine that the isosceles triangle is an isosceles triangle?
2 interior angles are equal and 2 sides are of equal length.
What does isosceles triangle mean?
an isosceles triangle is a triangle that means two of the triangles sides have the same length and two angles are the same
