Question

Pls answer these questions

1 :Name the type of ∆ ABC if, AB = AC = 5.8 cm and BC = 7.7 cm

2 :Calculate the area of a parallelogram whose base is 15 m and height is 3 cm.

3: One of the acute angles of a right angled triangle is 35°. Find the measure of

the other acute angle of the triangle.

4:In ∆ STU, name the angle included between the sides TU and SU.

5A triangle can be constructed with sides having length 9 cm, 5.5 cm and 8cm. Is the statement right or wrong?

6 In ∆ DEF and ∆ XYZ, DE = XY, angle E = angle Y and EF = YZ. Name the
test of congruency by which both the triangles are congruent.

Answer 1

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
