Unit # 6 Geometry

Some Important concepts about angles:

1. Right Angle: An angle which measure 90 degree is called right angle.

2. Acute Angle: All the angles which measure less than 90 degree are called acute angles.

3. Obtuse Angle: All the angles which measure greater than 90 degree but less than 180 degree are called obtuse angles.

4. There are 360 degree in a circle.

5. There are 180 degree in a half circle.

6. There are 90 degree in a quarter circle.

7. Radius of a circle: The line segment which joins any point on the circle to its center is called radial segment of the circle. The length of radial segment is called radius of circle and is represented by "r".

8. Diameter of a circle: The line segment which joins any two points on a circle and passes through its center is called diameter.

9. Circumference of a circle: Distance covered in one revolution is equal to circumference of the circle.

10. Perimeter (of a room) : The total length of the boundary of a room is called its perimeter.

Perimeter (of a figure): The total length of the surroundings of a closed figure is called the perimeter.

11. Geometrical Shapes: a) Cube: A cube has 8 vertices, 6 surfaces, 12 edges. The length, height, and width of the cube are the same.

b) Cuboid: A cuboid has 8 vertices, 6 surfaces, 12 edges. All the surfaces of a cuboid are of rectangular shape.

c) Sphere: 0 vertices, 1 surface, 0 edges.

d) Cylinder: 0 vertices, 3 surface, 2 edges. It has 3 surfaces, one curved and the two circular.

e) Cone: 1 vertices, 2 surface, 1 edge. It has two surfaces, one curved and the other circular.

f) Pyramid: 5 vertices, 5 surfaces, 8 edges. Pyramid has five surfaces, one square and four triangular.

Answer: muscles.

2. The muscles are ________ and pink or ______ in color.

Answer: soft, red.

3. Muscles work with the bones and ________

Answer: joints..

4. Muscles ____________ food through the digestive system.

Answer: move

5. The main function of the bones of the skull along with the surrounded meninges, is to provide ___________

Answer: protection and structure

6. The _______ form the main structure of the thoracic cage protecting the thoracic organs

Answer: ribs

7. which three body parts are in pairs?

Ans: Pair of; Lungs, ovaries, te**es, kidney, eyes, salivary glands 3 in nose, mamary glands, Ni***es, legs ,hands.

8. do all the teeth have the same shape?

Ans: incorrect! Your teeth are different sizes and shapes because they each play a different, unique role in the food-chewing process.

9. what is the difference between molar and premolar teeth?

Ans: The main distinctions between premolar and molar teeth are in their size and shape. While a molar has four cusps or points, a premolar has two to three. While premolars are larger and wider than your more narrow canine teeth and have a flat surface area, molars are significantly larger than their bicuspid neighbors.

10. what is the number of teeth in human?

Ans: A normal adult mouth has 32 teeth.
