Question Analysis

The main focus is to identify the triangle where the altitude (height) is drawn with respect to the given base. We need to understand the concept of an altitude and match it with the visual representation in the provided triangles.

 

Key Concept Explanation

An altitude of a triangle is a line segment drawn from a vertex perpendicular to the opposite side (the base). It represents the height of the triangle with respect to that base.

 

Step - by - Step Solution

1. Analyze each triangle:

For the first triangle, the dashed line is drawn from vertex  perpendicular to the base . This meets the definition of an altitude with respect to base .

For the second triangle, the dashed line is perpendicular to the base
