The intersection of the arcs is the third vertex of the triangle. Take a point P at a distance of 7 cm from the centre of a circle of radius 2.5 cm and from the point P, draw two tangents PA and PB to the circle. Also write the steps of construction. What is the minimum distance each should walk so that each cancover the same distance in complete steps?12. Where. What is the length of the base? You also know that the angle between the sides is 50 degrees. For the triangle of area of 12 sq.cm., the height from the 8 cm side should be 3cm. Measure the length of each tangent. draw Isosceles Triangle: when we draw a isoceles triangle, angles are congruent i.e., an angles of each sides are equal. From both ends of segment QR, that is Q and R,Such that PQ=QR, mark arc at a distance of. ... Construct an isosceles triangle whose base is 8 cm and altitude 4 cm and then another Draw an equilateral triangle whose each side is 4.5 cm. h is the altitude of the triangle. From point B draw an arc of 8 cm radius. Step 3: Join A to C and B to C. ABC is the required isosceles triangle. The base is the unequal side of the triangle and the altitude is the perpendicular height from the base to the apex. Draw a line segment AB of length 7 cm. You can use a ruler or your compass set to the appropriate length to measure. 2. IF HCF of 65 and 117 is expressible in the form 65n - 117, then find the value of n.On a morning walk, three persons step out together and their steps measure 30 cm, 36 cmand 40 cm respectively. .​, प्रश्न 2.
