When a straight ladder is too close to a contact surface ,it strengthens the ladder's stability. True False

## Step 1<br />The problem statement is a statement about the stability of a ladder when it is placed too close to a contact surface. The statement is that when a ladder is too close to a contact surface, it strengthens the ladder's stability.<br />## Step 2<br />To determine the truth of this statement, we need to consider the principles of physics and the mechanics of ladder stability. <br />## Step 3<br />When a ladder is placed too close to a contact surface, it can cause the ladder to become unstable. This is because the ladder is not properly supported, and the contact surface can cause the ladder to tip over.<br />## Step 4<br />Therefore, the statement that when a ladder is too close to a contact surface, it strengthens the ladder's stability is false.
