the two equal angles in the isosceles triangle are the two long sizes. but an isosceles triangle doesn't have to have two long side that are the same length.an isosceles triangle is jus t supposed to have 2 long sides(does not have to be the same length), and one short side.To tell you I am a fifth grader and you can thank me for halping you.i am a girl
You can't tell. The only thing you know is that two of them are equal, and the third angle is (180 degrees minus the sum of the first two).
If its an isosceles triangle it has 1 line of symmetry but if its an equilateral triangle it has 3 lines of symmetry
One of the angles will be 90 degrees.
If it has a 90 degree angle and two acute angles then it is a right angle triangle.

Equilateral TriangleThree equal sidesThree equal angles, always 60°Isosceles TriangleTwo equal sidesTwo equal anglesScalene TriangleNo equal sidesNo equal anglesThere are three special names given to triangles that tell how many sides (or angles) are equal.There can be 3, 2 or no equal sides/angles:
If if is a triangle, it is isosceles. There's nothing more that I can tell you based on your question.
One can tell what a scalene triangle looks like by looking at each side of the triangle. A scalene triangle normally has very different length in each of its sides. It has no equal sides, and no equal angles.
right triangle forms a 90 degree angle scalene triangle has no congruent sides isosceles triangle has at least 2 congruent sides equilateral triangle has 3 congruent sides acute triangle all angles measure less than 90 degrees and the obtuse triangle contains 1 obtuse angles.

A right triangle is a triangle that has one 90 degree angle, and 2 other angles. Some special ones are 45-45-90, and 30-60-90. The sum of the angles in a triangle will always = 180 degrees. Since we know a triangle has 3 angles, and in particular, a right triangle has a 90 degree angle. We can say 180 degrees - 90 degrees = the other 2 angles. Add the other 2 angles in your triangle. Usually one is given as 90 degrees, or has a small square mark in the corner of the triangle to indicate that it is a right triangle. Once you add the other 2 angles, see if they add up to 90 degrees. If they do, you have a right triangle. If they do not, you either do not have a right triangle OR your triangle is broken and all 3 angles do not add up to 180 degrees.
If it has a 90 degree angle and two acute angles then it is a right angle triangle.
It's hard to tell, since there really is no such thing as "parallel angles". One thing we do know for sure . . . a triangle can't have two parallel sides.
