1. base angles

2. centroid

3. altitude of a triangle

4. orthocenter

5. vertex angle

6. median of a triangle

7. base of an isosceles triangle

1.Base angles.

2.Centroid.

3.Altitude of a triangle.

4. Orthocenter.

5.Vertex angle.

6.Median of triangle.

7. Base of an isosceles triangle.

Step-by-step explanation:

1. Base angles: The two angles that include the base of an isosceles triangle.

2. Centroid: A point on the interior of a triangle in which the three medians of the triangle intersect.

3.Altitude of a triangle:A segment from a vertex perpendicular to the opposite side.

4.Orthocenter: A point in which the three altitudes of the triangle intersect .It is possible for the orthocentre to occur on the triangle ,on the interior of the triangle or on the exterior of the triangle.

5.Vertex of angle:The angle formed by the two equal sides of an isosceles triangle.

6.Median of triangle:A segment from a vertex to the midpoint of the opposite side .

7.Base of an isosceles triangle: The third , unequal side of an isosceles triangle.

a. 3/4 ÷ 1/8 = 6

step-by-step explanation:

in the question, the number line represents 3/4 divided into 6 equal units. each arrow represents a unit and there are a total of six arrows.

the size of each unit is 1/8 as shown.

showing that 1/8 divides 3/4 into 6 divisions:

3/4 ÷ 1/8

= 3/4 x 8/1

= 3/1 x 8/4

= 3 x 2

= 6

hence, the number line represents six divisions given by 3/4 ÷ 1/8.
