CBSE Class 10 Maths Constructions
Constructions is the chapter dealing with practical geometry in CBSE Class 10 Maths. Students get to learn about constructing similar triangles, dividing a line segment into two or more parts, drawing tangents to a circle, drawing a tangent to a circle from a point outside the circle, and drawing a tangent to a circle from a point on the circle. This chapter in CBSE Class 10 Maths was brought to engage students in dealing with practical geometry concepts and enjoying mathematics while studying. Therefore, this chapter in practical geometry is both theoretical and practical.

Division of a Line SegmentDivision of a line Segment
Constructions of Similar TrianglesScale factor is the ratio of the size of the new figure (which will be constructed) to that of the given figure.
The scale factor may be < 1 or > 1.
If the scale factor is < 1, then the new figure will be smaller in size to the given figure.
If the scale factor is > 1, then the new figure will be greater in size to the given figure.
Taking scale factor into consideration we divide a line segment in the specified ratio and use it to draw a triangle, similar to a given triangle, with sides proportional to the sides of given triangle.
Construction of TangentsA tangent is perpendicular to the radius through the point of contact.
Number of tangents from a point on the circle is only one.
Number of tangents from a point outside the circle is two.
The two tangents to the circle from a point outside the circle are equal in length.
