Problems on Pedal Triangle and Excentre Triangle

Excentre of a Triangle

Problems Based on Triangle Inequality

A triangle having all sides of different length is known as scalene triangle (b) isosceles triangle an equilateral triangle (d) an acute triangle

Pedal Triangle and Ambiguous Case

Explain the following terms: Triangle (ii) parts or elements of a triangle Scalene triangle (iv) isosceles triangle Equilateral triangle (vi) acute triangle Right triangle (viii) obtuse triangle Interior of a triangle (x) exterior of a triangle.

A triangle whose two sides are equal is known as acute triangle (b) an isosceles triangle a scalene triangle (d) a right triangle

A triangle whose all sides are equal is called an equilateral triangle (b) an acute triangle a right triangle (d) an isosceles triangle

The circumcentre of the triangle lies within the triangle only when the triangle is :

If R_1 is the circumradius of the pedal triangle of a given triangle A B C ,a n dR_2 is the circumradius of the pedal triangle of the pedal triangle formed, and so on R_3,R_4 then the value of sum_(i=1)^ooR_i , where R (circumradius) of A B C is 5 is 8 (b) 10 (c) 12 (d) 15

A triangle whose on two sides are equal is called an acute triangle (b) a scalene triangle an isosceles triangle (d) an equilateral triangle
