No, because we can double the length of the sides of the 345 triangle and still have a rightangled triangle its sides will be 6810 and we can check that 10 2 = 6 2 8 2 Continuing this process by tripling 345 and quadrupling and so on we (ii) 3 cm, 8 cm, 6 cm Given sides 3 cm , 8 cm , 6 cm Using Pythagoras theorem , (Hypotenuse)2 = (Height )2 (Base)2 Here , Hypotenuse Is largest side that is 8 cm Since LHS ≠ RHS , Pythagoras theorem is not satisfied Hence the given triangle is not a right angled triangle Ex 65,1 Sides of triangles are given belowWhich pair of angles are congruent?

A triangle with angles of 30°, 60°, and 90° an angle of 90° a triangle with a side measuring 3, next an angle of 60°, and next a side measuring 4 a triangle with sides of 6, 8, and 10 a triangle with sides of 3 and 4 a triangle with a side measuring 4, next an angle of 90°, and next a side measuring 3 I would be grateful for any assistanceStep 2 Yes, it is a 345 triangle for n = 2 Step 3 Calculate the third side 5n = 5 × 2 = 10 Answer The length of the hypotenuse is 10 inches Example 2You decide to use 300, 400 and 500 cm lines Draw a 300 line along the wall Draw an arc 400 away from the start of the 300 line Draw an arc 500 away from the end of the 300 line Connect from the start of the 300 line to where the arcs cross
The 345 right triangle is the smallest right triangle that has all integer values Watch for it on the SAT and ACT, especially in questions related to trigA = α = 368 7 ° = 36°52'12″ = 064 4 rad Angle ∠The sides of a triangle are in the ratio of 456 Find the size of the largest angle in the triangle The angles will be the same no matter what sides we use, and long as they are in the ration 456 So we may as well take the easiest situation, which is to
234 Chapter 5 Congruent Triangles Finding an Angle Measure Find m∠JKM SOLUTION Step 1 Write and solve an equation to fi nd the value of x (2x Apply the Exterior Angle Theorem− 5)° = 70° x° x = 75 Solve for x Step 2 Substitute 75 for x in 2x − 5 to fi nd m∠JKM 2x − 5 = 2 ⋅ 75 − 5 = 145 So, the measure of ∠JKM is 145° To prove certain theorems, you may need to add a= 3(2) 4(2) ?Therefore, a 3 4 5 right triangle can be classified as a scalene triangle because all its three sides lengths and internal angles are different Remember that a 345 triangle does not mean that the ratios are exactly 3 4 5;

The ratio of the measures of two complementary angles is 54 What is the measure of the larger angle?B = β = 531 3 ° = 53°7'48″ = 092 7 rad Angle ∠ The 345 triangle is the best way I know to determine with absolutely certainty that an angle is 90 degrees This rule says that if one side of a triangle measures 3 and the adjacent side measures 4, then the diagonal between those two points must measure 5 in order for it to be a right triangle Confused yet?
