Q3: The sides of a triangular field are 35 m, 60 m and 110 m. Find the length of the
wire required to fence the field.
answer-It is given that the sides of a triangle field are 35 m, 60 m and 110 m. We need to find the length of wire required to fence the field. It means we need to find the perimeter of the triangular field. Therefore, 205m wire is required
Q4: Define:
(b) Parallel lines
ans- In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. ... A line and a plane, or two planes, in three-dimensional Euclidean space that do not share a point are also said to be parallel.
(c) Perpendicular lines
ans-In elementary geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle. The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle
(a) Intersecting lines
and-In Euclidean geometry, the intersection of a line and a line can be the empty set, a point, or a line. Distinguishing these cases and finding the intersection point have use, for example, in computer graphics, motion planning, and collision detection
Q5: Draw a line EF and take a point P above EF. Draw a line GH passing through P such
that GH EF.
