How do you find the sides of a right angled isosceles triangle when you know the angles?

You cannot.
A right angled isosceles triangle will always be 90-45-45 so knowing the angles does not add any information. Without knowledge of any one side, you cannot distinguish between the infinitely many similar 90-45-45 triangles.

How many pairs of perpendicular lines does an isosceles triangle have?
There can be only one pair of perpendicular lines in an isosceles triangle when it is a right angled isosceles triangle. A non right angled isosceles triangle has no pairs of perpendicular lines.
Classify the triangle by its angles and by its sides?
All angles equal = all sides equal = equilateral. Two angles equal = two sides equal = isosceles. All angles different = all sides different = scalene. An isosceles or scalene triangle may be right-angled or obtuse-angled if one of its angles is a right angle or obtuse angle (respectively).
Can a right angled triangle sometimes be a equilateral triangle?
No, since an equilateral triangle has three congruent angles of 60 degrees, and a right triangle must have an angle of 90 degrees. However, a right triangle may be an isosceles triangle.
What type of triangle has one side twice as long as the other side?
A right triangle. * * * * * Not necessarily. All that can be said is that is is not an equilateral triangle. It can be isosceles or scalene. It can be acute angled, right angled or obtuse angled.
What is a plane triangle?
a plane triangle is a normal triangle, like the isosceles, right angled, equilateral and scalene triangle.
How do you find the measures of the angles in a right isosceles triangle?
If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.
A triangle has two 45 degree angles what kind of triangle is it?
Isosceles Triangle * * * * * In fact it is a right angled isosceles triangle.
Which triangle is not an isosceles triangle?
An obtuse triangle or a right angle triangle. An equilateral is definitely an isoceles triangle * * * * * Not true. An obtuse or right angled triangles can be isosceles. It depends on the sizes of the two smaller angles. An isosceles triangle has two equal angles so a triangle with angles of size [A, (180-A)/2, (180-A)/2] degrees where 90 < A < 180 degrees would be an obtuse angled isosceles triangle. A triangle with angles of size (90, 45, 45) degrees is a right angled isosceles triangle.
A triangle that has angles that measures 45 45 and 90degrees is an?
An isosceles right angled triangle
Can an isosceles triangle have a right angle?
Yes, when it has a 90 degree and two 45 degree angles it is an isosceles right angled triangle.
What angles does a isoscles triangle have for example right angles or obtuse or acute?
Any of the above: you can have a right-angled isosceles (not isoscles!) triangle, or an obtuse-angled one or an acute angled-one.
What triangle appers to be both right and isosceles?
a right angled triangle with the remaining angles both being 45 degrees will be a rightangled triangle and an isosceles triangle.
Can a triangle have two 45 degrees angles?
Yes, it would then be an isosceles right angled triangle.
When does right-angle triangle have least hypotenuse?
When it is an isosceles right angled triangle: with angles that are 90-45-45.
Can isosceles triangle be also right angled triangle?
Yes. A triangle with angles of 90-45-45 degrees.
What is a Right angled isosceles triangle?
A triangle with a 90 degree angle and two 45 degree angles.
What kind of triangle has two 45 degree interior angles?
right triangle * * * * * Or, to be more precise, a right-angled isosceles triangle.
