Bisectors of one internal angle and other two opposite exterior angles are ____________.
Radius and tangent of a circle are ______________ to each other.
Circum-radius of a circle is denoted by ____________.
In-radius of a circle is denoted by ____________.
For the circum circle, ____________ of sides of a triangle are drawn.
a) Parallel Bisectors
b) Right Bisectors
c) Perpendicular Bisectors
d) Congruent Bisectors
If sum of measure of two sides of a triangle is less than the measure of the third side, it is not possible to construct the triangle
The angle inscribed in a semi circle is always obtuse angle.
Angle bisectors of a triangle are always concurrent.
In-circle of a triangle touches three vertices
The line segment joining mid point of a side to opposite vertex is called altitude
The right bisectors of sides of a triangle intersect in ratio of 2:1.
The median is the right bisector of side of the triangle.
Right bisectors of the sides of a triangle are not concurrent.
Only one tangent can be drawn from a point outside the circle.
The bisectors of one interior and two exterior angles of a triangle are not concurrent.
The center of inscribed circle of a triangle is equidistant from its vertices
The centre of circum circle of a triangle is equidistant from its vertices.
An in circle of a triangle does not touch the sides of a triangle internally.
Direct common tangent touches the two circles in such a way that both circles are on one side of the tangent
A line bisecting an angle is called altitude.
