True or false Assume ray lies inside the angle ADB?
False
If the median to a side of a triangle is also an altitude to that side then the triangle is isosceles How do you write this Proof?
Let the triangle be ABC and suppose the median AD is also an altitude.AD is a median, therefore BD = CDAD is an altitude, therefore angle ADB = angle ADC = 90 degreesThen, in triangles ABD and ACD,AD is common,angle ADB = angle ADCand BD = CDTherefore the two triangles are congruent (SAS).And therefore AB = AC, that is, the triangle is isosceles.
What is the proof that equiangular triangle is also called equilateral triangle?
Label the triangle ABC. Draw the bisector of angle A to meet BC at D. Then in triangles ABD and ACD, angle ABD = angle ACD (equiangular triangle) angle BAD = angle CAD (AD is angle bisector) so angle ADB = angle ACD (third angle of triangles). Also AD is common. So, by ASA, triangle ABD is congruent to triangle ACD and therefore AB = AC. By drawing the bisector of angle B, it can be shown that AB = BC. Therefore, AB = BC = AC ie the triangle is equilateral.
True or false Assume ray lies inside the angle ADB?
False
An exterior angle of triangle BDC is?
<ADB
When Given point b is the interior of angle adc conjecture adb is congruent to bdc.?
False; just because it is in the interior does not mean it is on the bisecting line.
A rectangular field abcd is shown the length of the field ab equals 160cm the width of the field bc equals 75cm calculate the size of angle adb?
bc = ad = 75 Tan adb = 160/75 = 2.1333 (4dp), so angle adb = 64.885°.
In this parallelogram angle bad equals 70 dergrees and angle adb equals?
55 degrees
Angle bisector of angleA of triangleABC is perpendicular to BC prove it is isosceles?
Let D represent the point on BC where the bisector of A intersects BC. Because AD bisects angle A, angle BAD is congruent to CAD. Because AD is perpendicular to BC, angle ADB is congruent to ADC (both are right angles). The line segment is congruent to itself. By angle-side-angle (ASA), we know that triangle ADB is congruent to triangle ADC. Therefore line segment AB is congruent to AC, so triangle ABC is isosceles.
How do i prove if the base angles of a triangle are congruent then the triangle is isosceles?
Suppose you have triangle ABC with base BC, and angle B = angle C. Draw the altitude AD.Considers triangles ABD and ACDangle ABD = angle ACD (given)angle ADB = 90 deg = angle ACDtherefore angle BAD = angle CADAlso the side AD is common to the two triangles.Therefore triangle ABD is congruent to triangle ACD (ASA) and so AB = AC.That is, triangle ABC is isosceles.
What is ADB for coal?
ADB. Its means Air Dry Basis.

What is they meaning of ADB of bpi?
The meaning of ADB is Average Daily Balance.
What are coal ARB and ADB?
ADB=Air Dried Basis ARB=As Received Basis
What dose adb stand for in sbi adb?
In the case of SBI, ADB in relation to a branch refers to Agricultural Development Branch - such branches concentrate on development of agricultural lending in their areas.
