Answers Parallelogram, square, rectangle, rhombus Isosceles triangle and the obtuse angle is 110°. 8 edges and 5 vertices Rotational symmetry No rotational symmetry One or more pairs of diagonally opposite angles Rhombus Kite are equal No pairs of diagonally Trapezium opposite angles are equal Cuboid and cube A scalene triangle has three sides of different lengths and no angles are equal. No, she is not correct as a cube has 6 faces, 8 vertices and 12 edges. Triangular-based pyramid 25° (acute), 35° (acute) and 120° (obtuse) 8 cm2 Extension Surface area of the first box = 1862 inches2. Surface area of the second box = 1931 inches2. The second box has the largest surface area by 69 inches2.
