List of practice Questions

If two circles touch each other externally, then what is the number of common tangents?
From an external point \( P \), two tangents \( PA \) and \( PB \) are drawn to a circle. If \( PA = 6 \) cm, then \( PB \) is:
If three points are collinear then what is the area of the triangle formed by them?
If \( A(-1,0) \), \( B(5,-2) \), and \( C(8,2) \) are the vertices of a triangle \( \triangle ABC \), then the coordinates of its centroid are:
If in \( \triangle ABC \), \( AD \) is the bisector of \( \angle BAC \) and \( AB = 10 \) cm, \( AC = 14 \) cm, \( BC = 6 \) cm, then the value of \( DC \) is:
In \( \triangle ABC \), \( DE \parallel BC \) such that \( \frac{AD}{DB} = \frac{3}{5} \). If \( AC = 5.6 \) cm, then \( AE \) is:
If the ratio of corresponding sides of two similar triangles is \( 5:6 \), then the ratio of their perimeters is:
In \( \triangle ABC \), \( AB = 6\sqrt{3} \) cm, \( AC = 12 \) cm, and \( BC = 6 \) cm, then \( \angle B \) is:
If \( P \left( \frac{a}{2}, 4 \right) \) is the midpoint of the line segment joining the points \( A(-6,5) \) and \( B(-2,3) \), then the value of \( a \) is:
