Angles of a Triangle Test-1 Solutions

Solution of Problem 1 :

If the angle B is x, then the CBD angle is x-a. From the sum of the angles of the DBC triangle, x = 37 °

Solution of Problem 2 :

From the sum of the angles of the US triangle, x + n = 180 ° -m (ADB), in the ADC triangle from the outer angle y + n = m (ADB). Multiply the second expression by (-2) and add xy = 180 to the side by the first. ° -2m (ADB). If 32 ° is written instead of x, m (ADB) = 74 °.

Solution of Problem 3 :

The size of the angle formed when one side of the triangle is bent inward is x = a + b + c. The US concave quadrilateral contains x + a + 40 ° -a = 90 ° (shalwar, rocket, missile rule), x = 50 °. See geometry proofs section for proof of rule-Rocket rule-Missile rule and other proofs.

Solution of Problem 4 :

The size of the angle formed by the two inner bisectors in a triangle is 90 degrees more than half the size of the inside angle in the third corner, so 6x = 90 ° + x, x = 18 °.

Solution of Problem 5 :

Let the extension [AB] and [DC] intersect at point K. With the rule of M, m (DKA) = 68 °. The dimension of the angle formed by the intersection of two bisector in the triangle AKD is x = 90 ° + (68 ° / 2) = 124 ° .

Solution of Problem 6 :

Since [AE] and [BD] are bisectors in triangle ABC, m (AFB) = 90 ° + (x / 2). If the angles of the quadrant equal 360 °, then x = 34 °.

Solution of Problem 7 :

The measure of the angle formed by the two outer bisectors in a triangle is the complement of half the measure of the angle in the third corner. 11x = 90 ° – (14x / 2), x = 5 °.

Solution of Problem 8 :

The angle between the two outer bisectors is x = 90 ° – (44 ° / 2) = 68 °.
