00:00 Which leg has both height and median?
00:03 AD is perpendicular to BC (forms a right angle with it)
00:07 EF bisects AB but it's not a median (doesn't originate from a vertex)
00:10 Therefore there is no leg that has both a median and a perpendicular
00:13 And this is the solution to the question

Step-by-step solution

To solve this problem, we'll verify which side or sides have the height and the median based on their definitions.

First, we identify what constitutes a height in the triangle. A height, or an altitude, is a perpendicular line segment from one vertex to the opposite side or its extension. In many triangles, this is represented by a line that intersects at a right angle with the side it is drawn to.

The median of a triangle is a line segment drawn from a vertex to the midpoint of the opposite side. It divides the opposite side into two equal parts.

Now, we'll analyze the given diagram:

  • Examine the triangle ABC and any drawn perpendicular lines that represent heights.
  • Check for lines that extend from a vertex and bisect the opposite side, indicating medians.

Upon reviewing the diagram, there appear to be no segments that are clearly perpendicular from a vertex to the opposite side, suggesting no height is drawn. Similarly, there is no indication of a line from a vertex bisecting the opposite side, suggesting no median is concretely drawn either.

Therefore, based on this analysis, we conclude that no sides have the height or median explicitly drawn to them in this diagram.

The correct choice, given this information, is: No sides.

Final Answer

No sides

Key Points to Remember

Essential concepts to master this topic
  • Height Definition: Perpendicular line from vertex to opposite side
  • Median Definition: Line from vertex to midpoint of opposite side
  • Visual Check: Look for right angle symbols and midpoint markers ✓

Common Mistakes

Avoid these frequent errors
  • Assuming every line segment is a height or median
    Don't assume lines from vertices are automatically heights or medians = wrong identification! Just because a line connects a vertex to the opposite side doesn't make it special. Always check for perpendicular symbols (right angles) for heights and midpoint markers for medians.

FAQ

Everything you need to know about this question

How can I tell if a line is a height in a diagram?

+

Look for a right angle symbol (small square) where the line meets the opposite side. Heights are always perpendicular, forming 90° angles with the base.

What shows that a line is a median?

+

A median connects a vertex to the midpoint of the opposite side. Look for equal tick marks or measurements showing the side is divided into two equal parts.

Can a line be both a height and a median?

+

Yes! In special triangles like isosceles or equilateral triangles, the same line segment can serve as both a height and median from certain vertices.

What if I don't see any special markings in the diagram?

+

If there are no right angle symbols or midpoint markers, then likely no heights or medians are specifically drawn. Don't assume unmarked lines have special properties!

Why is the answer 'No sides' for this problem?

+

Looking at the diagram, the segments from vertices don't show perpendicular symbols for heights or midpoint markers for medians. Without these visual indicators, we cannot identify any drawn heights or medians.
