Solving isosceles and equilateral triangles worksheet
Which side of ΔPQR should be equal to side AB of ΔABC so that the two triangles are congruent? Give reason for your answer.įor the triangle to be congruent, we must AB = QR. In triangles ABC and PQR, ∠A= ∠Q and ∠B = ∠R. Which of the following is not a criterion for congruence of triangles?ġ.

In a triangle, angle opposite to the longer side is larger (greater).A point equidistant from two intersecting lines lies on the bisectors of the angles formed by the two lines.A point equidistant from two given points lies on the perpendicular bisector of the line segment joining the two points and its converse.RHS stands for right angle – Hypotenuse side. For example: ΔABC and ΔPQR shown below satisfy RHS congruence criterion. RHS Congruence Rule – If in two right triangles the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle then the two.SSS congruence Rule – If three sides of one triangle are equal to the three sides of another triangle then the two triangles are congruent for example ΔABC and ΔDEF as shown in the figure satisfy SSS congruence criterion.Each angle of an equilateral triangle is 60o.Sides opposite to equal angles of a triangle are equal.Angle opposite to equal sides of a triangle are equal.Isosceles Triangle – A triangle in which two sides are equal is called an isosceles triangle.įor example: DABC shown below is an isosceles triangle with AB=AC.AAS criterion for congruence of triangles is a particular case of ASA criterion.AAS Congruence Rule – Two triangle are congruent if any two pairs of angles and one pair of corresponding sides are equal for example ΔABC and ΔDEF shown below satisfy AAS congruence criterion.For examples ΔABC and ΔDEF shown below satisfy ASA congruence criterion. ASA Congruence Rule – Two triangles are congruent if two angles and the included side of one triangle are equal to two angles and the included side of other triangle.For example: ΔABC and ΔPQR as shown in the figure satisfy SAS congruent criterion SAS congruency rule – Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of the other triangle.

Congruent figures – Congruent means equal in all respects or figures whose shapes and sizes are both the same for example, two circles of the same radii are congruent.A triangle has three sides, three angles and three vertices. Triangle – A closed figure formed by three intersecting lines is called a triangle.Chapter-wise Class 9 Mathematics Triangles Worksheets Pdf Download This is the best collection of Mathematics Triangles standard 9th worksheets with important questions and answers for each grade 9th Mathematics Triangles chapter so that the students are able to properly practice and gain more marks in Class 9 Mathematics Triangles class tests and exams.
