Answer:
B and D
Step-by-step explanation:
This must be a six sided figure
A. 15 x 15. This would be area
B. 6 x 15. This is the sum of six sides of 15
C. 15 + 6. This is the sum of 2 sides of different length
D. 15 + 15 + 15 + 15 + 15 + 15. This is the sum of six sides of length 15
The intersection of altitudes traced perpendicularly from a triangle's vertices to its opposite sides is known as an orthocenter.
Given that,
We have to find what is orthocenter.
We know that
<h3>What is Orthocenter?</h3>
The intersection of altitudes traced perpendicularly from a triangle's vertices to its opposite sides is known as an orthocenter. It is the location in a triangle where the three angles of the triangle intersect. An orthocenter's three primary characteristics are as follows:
Triangle: A three-sided polygon with three edges.
A triangle's height is the line that runs between its vertices and perpendicular to the other side. A triangle can therefore have three heights, one from each vertices.
Vertex - A vertex is the intersection of two or more lines.
