How many sides does a right angle triangle have?
It has 2 equal sides of right triangle.
What does all the triangles look like and what type of triangle are they?
There are infinitely many types of triangles, and they can be classified according to their angles or sides (or both). Equilateral (equiangular triangles): All sides equal, all angles 60 degrees. Obtuse angled isosceles triangles: Two sides equal; one angle > 90deg. Right angled isosceles triangles: Two sides equal; angles of 90, 45, 45 degrees. Other isosceles triangle: Two sides equal; angles of 180-2x, x, x degrees. Obtuse angled scalene triangles: All sides unequal, one angle > 90 degrees. Right angled scalene triangles: All sides unequal, one angle = 90 degrees. Acute angled scalene triangles: All sides unequal, all angles < 90 degrees.
What shape has no equal angles or equal sides?
There are infinitely many possible shapes. Apart from a scalene triangle, none have a specific name. They are irregular polygons, but that is not enough. Irregular polygons can have equal sides (if there is at least one angle that is not equal to the rest) or equal angles (if there is at least one side that is not equal to the rest).
How many sides does an isosceles triangle have that are congruent?
An isosceles triangle has exactly two sides which are equal. (The word congruent usually applies to triangles, not sides.)
How do you prove triangles are congruent if you only have expressions for side and angle measures?
How many sides of each triangle and how many angles of each triangle do you have ? If you have two sides and the angle between them, or two angles and the side between them, equal to the same parts of the other triangle, then your triangles are congruent. You don't even have to know what the actual numbers are. If the expressions are equal, then the sides or angles are equal.
How many sides of equal length are on an isosceles triangles?
two
How many sides does the equalatiral triangle have?
All triangles have three sides... Equilateral trianles have three EQUAL sides.
How many sides does a right angle triangle have?
It has 2 equal sides of right triangle.
How many equilateral triangles are there?
As many as you like providing they have 3 equal interior angles and 3 equal sides in length.
How many sides does an equilateral triangle have?
All triangles have exactly three sides. This is true whether the triangle is equilateral or not. If the triangle is equilateral, then the three sides will all be equal in length.All triangles have three sides.

How many triangles are in a pentagon and how many sides?
A pentagon has 3 triangles and 5 sides
How many sides does a triangular pryimed have that are triangles?
it has 4 sides that are triangles
How many sides does an isosceles triangle have that are congruent?
An isosceles triangle has exactly two sides which are equal. (The word congruent usually applies to triangles, not sides.)
How many triangles exist with the given side lengths 4cm 4cm 7cm. Only one triangle No triangles or infinite triangles?
It is an isosceles triangle with 2 equal sides.
How do you prove triangles are congruent if you only have expressions for side and angle measures?
How many sides of each triangle and how many angles of each triangle do you have ?
