Summary Problems 4

Problem : The legs of a right triangle are both of length 2. How long is the hypotenuse? Problem : Decide whether the triangle below is a 30-60-90 triangle, a 45-45-90 triangle, a right triangle with different angle measures than these, or not a right triangle at all.

30-60-90 triangle

Problem : Decide whether the triangle below is a 30-60-90 triangle, a 45-45-90 triangle, a right triangle with different angle measures than these, or not a right triangle at all.

45-45-90 triangle

Problem : Decide whether the triangle below is a 30-60-90 triangle, a 45-45-90 triangle, a right triangle with different angle measures than these, or not a right triangle at all.

Right triangle

Problem : Decide whether the triangle below is a 30-60-90 triangle, a 45-45-90 triangle, a right triangle with different angle measures than these, or not a right triangle at all.

Unknown. If x = 45 degrees, then it is a 45-45-90 triangle. If x does not equal 45 degrees, then it is not a right triangle.
