Triangle Height Verification: Identifying the Perpendicular Line to Base

Question

Is the straight line in the figure the height of the triangle?

Video Solution

Solution Steps

00:00 Determine whether the straight line in the drawing is a height in the triangle
00:02 A height in a triangle extends from one of the triangle's vertices and is perpendicular to the side
00:05 Therefore this line is the height, and this is the solution to the question

Step-by-Step Solution

To determine if the straight line is the height of the triangle, we'll analyze its role within the triangle:

  • Step 1: Observe the triangle and the given line. The triangle seems to be made of three sides and a vertical line within it.
  • Step 2: Recall that the height of a triangle, in geometry, is defined as a perpendicular dropped from a vertex to the opposite side.
  • Step 3: Examine the positioning of the line: The vertical line starts at one vertex of the triangle and intersects the base, appearing to be perpendicular.
  • Step 4: Verify perpendicularity: Given that the line is shown as a clear vertical (and a small perpendicular indicator suggests perpendicularity), we accept this line as the height.
  • Step 5: Conclude with verification that the line is effectively meeting the definition of height for the triangle in the diagram.

Therefore, the vertical line in the figure is indeed the height of the triangle.
