Proof of thales theorem class 10
Let us now try to prove the basic proportionality theorem statement Consider a triangle ΔABC, as shown in the given figure. In this triangle, we draw a line PQ parallel to the side BC of ΔABC and intersecting the sides AB and AC in P and Q, respectively. According to the basic proportionality theorem as stated above, … See more Let us now state the Basic Proportionality Theorem which is as follows: If a line is drawn parallel to one side of a triangle intersecting the other two sides in distinct points, then the other … See more According to this theorem, if a line divides any two sides of a triangle in the same ratio, then the line is parallel to the third side. See more In a ∆ABC, sides AB and AC are intersected by a line at D and E respectively, which is parallel to side BC. Then prove that … See more WebGiven: BC = 14 cm. If F is the midpoint of AB and E is the midpoint of AC, then using the midpoint theorem: EF = 1/2 (BC) Substituting the value of BC, EF = (1/2) × 14. EF = 7 cm. Therefore, the value of EF = 7cm. 80,202. The Mid-Point …

WebA few important theorems are: Theorem 1: Equal chords of a circle subtend equal angles, at the centre of the circle. Converse of Theorem 1: If two angles subtended at the centre, by two chords are equal, then the chords are of equal length. Theorem 2: The perpendicular to a chord, bisects the chord if drawn from the centre of the circle.
