In two right triangles, one side and an acute angle of one are equal to the corresponding side and angle of the other, then ΔABC ≅ ΔDEF by the criterion
In ΔABC if ∠A = ∠B, then
In the given figure, AB = AC and ∠ACD = 105°, ∠BAC will be
PQR is a triangle in which PQ = PR and S is any point on the side PQ. Through S, a line is drawn parallel to QR and intersecting PR at T. then
The altitude of an equilateral triangle of side a to any of its other sides from the opposite vertex is
In an isosceles right angled triangle, the measures of the acute angles are
In ΔABC if AB = BC then:
Pick out the incorrect statement
If the bisector of the exterior vertical angle of a triangle is parallel to the base, then it is
In PQR, PQ = PR and R = 65°, then P = ?
By using the theorem,If two sides of a triangle are equal then the opposite angles to the sides are equal.
⇒ if PQ=PR then ∠Q=∠R
in triangle PQR,
⇒ ∠P+∠Q+∠Q=180° (∵∠Q=∠R)
