AB=8cm, then length of the segment joining mid points of AB and AC is
equal to *
4cm
10cm
6.5cm
2.5cm​

Answer 1

Answer:

a

Step-by-step explanation:

it will be half of the line segment AB

Answer 2

Answer:

In an isosceles triangle, BC=AC. Here AC=5cm, and AB=8cm. We should find the midpoints of AB and AC using the above value.

Final Answer: midpoint of AB and AC = DE = Option d: $2.5cm$

Step-by-step explanation:

From the following image,

• We draw the triangle ABC with the value AB $=8cm$, BC $=5cm$,

AC $=5cm$.

• Draw the midpoint of AB is D and the midpoint of AC is E.
• Here we will go to find the value of DE . DE is the midpoints of AB and AC.
• Here BC is parallel to DE. That is, BC ║ DE.
• Using Midpoint theorem,

                                $DE=\frac{1}{2} BC$

                                        $=\frac{1}{2}*5$ ⇒ $BC=5cm$

                                 $DE=2.5cm$

Final Answer: mid points of AB and AC: Option d: 2.5cm
