Answer:

1) isosceles triangle

2) 4500cm^2 or 0.45 m^2

3) 55 degrees

4) Angle SUT

5) Triangle Inequality Theorem - the sum of two side lengths of a triangle is always greater than the third side. If 8 cm is your third side, then the triangle could be constructed because 9 + 5.5 > 8.

6) SAS - Side Angle Side
