Example of Corner
In the given triangle, there are three lines AB, BC, and AC. The point A is the intersection
of two lines, BA and CA. Similarly, B is the intersection of AB and CB and C is the intersection
of AC and BC. So, A, B, and C are the three corners in the given triangle.
Solved Example on Corner
Ques: Choose the figures that have four corners.
Choices:
A. Figure 1 and Figure 3
B. Figure 2 and Figure 3
C. Figure 1 and Figure 4
D. Figure 2 and Figure 4
Correct Answer: A
Solution:
Step 1: A plane is a flat surface that extends in all directions.
Step 2: F, A, L, I, C lie on plane F and G, E, O, B lie on plane G. So,
the first statement is false. [A plane can be named either by a single capital
letter or by naming at least three non-collinear points in the plane.]
Step 3: Points G, E and F, A lie on two different planes. So, they are not Corner. So, second statement is false.
Step 4: O and A lie on two different planes. So, they are not Corner. Therefore, the third statement is also false.
Step 5 : Points F, A, L, I, C lie on the same plane and are Corner. So, the fourth statement is correct.
Quick Summary
