Question:
1. Find the area of a triangle with a base of 12 cm and a height of 15
cm.
2. Prove that a rectangle is a parallelogram.
3. Calculate the perimeter of a square with a side length of 10 cm.
4. Determine the equation of the line that passes through the point
(3,4) and is perpendicular to the line y = 2x + 1.
5. Find the volume of a cone with a radius of 6 cm and height of 8 cm.
6. Prove that the diagonals of a square are congruent.
7. Calculate the area of a circle with a radius of 5 cm.
8. Determine the equation of the line that passes through the point (5,-
2) and has a slope of 3.
9. Find the surface area of a cylinder with a radius of 5 cm and a height
of 10 cm.
10. Prove that the opposite angles of a parallelogram are congruent.
, Answer:
1. To find the area of a triangle, we use the formula: (base x height) / 2.
In this case, the base is 12 cm, and the size is 15 cm, so the area of the
triangle is (12 x 15) / 2 = 180 cm^2.
The base and height of a triangle are the two sides of the triangle that
form a right angle, or 90 degrees. In this specific example, the triangle's
base is 12 cm, and the height is 15 cm. To find the area of the triangle,
we multiply the base (12 cm) by the height (15 cm) and then divide the
result by 2. In this case, that would be (12 x 15) / 2 = 180 cm^2. This is
the final area of the triangle.
2. To prove that a rectangle is a parallelogram, we can use the following
properties of a rectangle and a parallelogram:
A rectangle has four right angles.
A parallelogram has opposite sides that are parallel.
A rectangle has congruent, opposite sides.
A parallelogram has congruent, opposite angles.
Using these properties, we can see that a rectangle satisfies all the
conditions of a parallelogram. Therefore, a rectangle is a parallelogram.
