equation of line two line and one point making a right angled triangle

Question 1 - Question: Can two vertically opposite angles be supplement to each other? Draw a diagram to illustrate your answer. Answer: Let AB and CD bisect each other at right angles as shown in figur..

and is of length p, is given by x cos a + y sin a = p. (Normal form) Every straight line has an equation of the form ax+by+c=0 and conversely an equation of the type ax+by+c=0 (a,b are both not equal to zero) always represents a straight line. T..

Theorem 2 (Converse of Theorem 1) - If two adjacent angles are supplementary, then their exterior arms lie in a straight line. are adjacent angles. AOB is a straight line..

There are two parallel lines. 8 points are marked on one and 5 on the other. How many triangles can be formed with these points as vertices? => 66 or 11200 or 286 or 220..

Point - It is an exact location. It is a fine dot which has neither length nor breadth nor thickness but has position i.e., it has no magnitude. It is denoted by capital letters A, B, C, O et..

A triangle has two congruent sides and one right angle. Classify the triangle. => isosceles right triangle or scalene triangle or equilateral triangle or None of the above..

Angle between two lines - Dividing throughout by x 2 , we get This being a quadratic in m has two roots m 1 and m 2..

Solution of Right Angled Triangles - To solve a right angled triangle, we need to find out the unknown sides and the angles with the help of t-ratios. To find a side, usually we take such t-ratios that involve the unknown sides. ..

Straight lines intersect at (X 1 ,Y 1..

Hence the point of intersection is Thus, the point of intersection is obtained by solving the two given equations..
