As many as you like but they will all be scalene triangles from the given interior angles that add up to 180 degrees.

Doesn't exist. No such thing.

Two perpendicular lines will meet in a right angle (90 degrees) if they exist on a flat plane.

It depends what time it is. Unless the clock is broken. Then it could be just about anything between 0 and 360 degrees. Anything except for 146.70001332 degrees. That angle just can't exist.

A quadrilateral triangle is an oxymoron.A quadrilateral has four sides, a triangle has three so a quadrilateral triangle cannot exist. You could therefore say that it has zero degrees.

No triangle exists with the given angle measures. None because the given angles add up to 190 degrees and the 3 angles in any triangle add up to 180 degrees.

40Â° + 25Â° + 115Â° = 180Â°, which is the correct total for the angles (in degrees) of a triangle. There are infinitely many triangles with those angles.

The hypotenuse is a side, not an angle. However, if you mean the angle across from the hypotenuse, it is always 90 degrees, or pi/2 radians because hypotenuses only exist in right triangles.

Doesnt exist!

Doesn't exist. No such thing.

Infinitely many could, but they would all be congruent to one another.

A triangle with interior angles of 42, 87 and 24 degrees doesn't exist because the angles add up to 153 degrees whereas the interior angles of any triangle always add up to 180 degrees.

An angle greater than 90 degrees would be considered an "obtuse" angle. Once you get to 180 they are considered "Straight" lines. Once you pass 180 degrees they are called "Reflex" angles.

Two perpendicular lines will meet in a right angle (90 degrees) if they exist on a flat plane.

Do exist.
