True or false? in order to inscribe a circle in a triangle, the circle's center must be placed at the circumcenter of the triang
Dvinal [7]

Answer:

<h2>False.</h2>

Step-by-step explanation:

A inscribe circle in a triangle means to draw the biggest circle possible inside such triangle. To do that perfectly, we first have to find the incenter of the circle, which is the intersection of all three internal bisector of the triangle, that point is the center of the inscribed circle.

Therefore, the statement is false.

In addition, a circumcenter allow to perfectly draw a circumscribed circle, which is outside the triangle, which is not the case here.

An image showing the inscribed circle is attached.

Calculate the area of triangle ABC with altitude, CD, given
defon

Answer:

37.5 square units

Step-by-step explanation:

Given:

A(-6,-4), B(6,5), C(-1,6), and D(2, 2), where CD is the altitude if ∆ABC

Required:

Area of ∆ABC

SOLUTION:

Area of a ∆ABC =½*AB*CD

✍️AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{6 -(-6))^2 + (5 -(-4))^2

AB = \sqrt{12^2 + 9^2}

AB = \sqrt{144 + 81}

AB = \sqrt{225} = 15

✍️CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{2 -(-1))^2 + (2 - 6)^2

CD = \sqrt{(3)^2 + (-4)^2}

CD = \sqrt{9 + 16}

CD = \sqrt{25} = 5

✍️Area of a ∆ABC =½*AB*CD

= ½*15*5

✅ Area = 37.5 square units
