What is the small box at the vertex of angle AOB indicates that angle AOB measures?
90 degrees
The parallelogram abcd is a rhombus what type of triangle is aob?
Right Triangle
What type of triangle is triangle AOB if the parallelogram ABCD is a rhombus?
it is a right triangle because a rhombus' diagonals are perpendicular
Prove that if chords of congruent circles subtend equal angles at their centers then the chords are equal?
let the two circles with centre O and P are congruent circles, therefore their radius will be equal. given: AB and CD are the chords of the circles with centres O and P respectively. ∠AOB=∠CPD TPT: AB=CD proof: in the ΔAOB and ΔCPD AO=CP=r and OB=PD=r ∠AOB=∠CPD therefore by SAS congruency, ΔAOB and ΔCPD are congruent triangle. therefore AB=CD
Given radius and chord length. What is the height of arc to midpoint of chord?
Draw the circle O, and the chord AB. From the center, draw the radius OC which passes though the midpoint, D, of AB. Since the radius OC bisects the chord AB, it is perpendicular to AB. So that CD is the required height, whose length equals to the difference of the length of the radius OC and the length of its part OD. Draw the radius OA and OB. So that OD is the median and the height of the isosceles triangle AOB, whose length equals to √(r2 - AB2/4) (by the Pythagorean theorem). Thus, the length of CD equals to r - √(r2 - AB2/4).
What is the small box at the vertex of angle AOB indicates that angle AOB measures?
90 degrees
What does AOB measure?
angle aob measure
What was the AOB setup?
The 'A-hole On Bender Setup' i believe....
What is the full form of AOB?
Any Other Business :)
The parallelogram abcd is a rhombus what type of triangle is aob?
Right Triangle
Aob has a measure of 90 and called a?
If the measurement is in degrees, it would be called a right angle.
Draw a involude for a semi circle of radius 25mm?
bisect a angle AOB 35
What type of triangle is triangle AOB if the parallelogram ABCD is a rhombus?
it is a right triangle because a rhombus' diagonals are perpendicular
What comes first in nitrification?
The first step in nitrification is the conversion of ammonia (NH3) to nitrite (NO2-) by ammonia-oxidizing bacteria (AOB).
What two factors cause nitrification to occur?
Nitrification occurs primarily due to the activities of two groups of microorganisms: ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB). AOB convert ammonia (NH3) to nitrite (NO2-) while NOB further oxidize nitrite to nitrate (NO3-), completing the nitrification process.
What is the length of arc AB if measured of AOB equals 240 and the radius is 4?
The equation for finding the length of an arc is S=rθ,where S is the arc length, r is the radius, and θ is the angle in radians.Assuming you mean AOB=240 is the angle of the arc you are measuring in degrees:θ=(pi*240)/180=4.1888radTherefore the arc length is 4cm*4.1888rad=16pi/3=16.76cm
The area of the region bounded by arc AB and line segment AB is found by taking the area of sector AOB and subtracting?
Unfortunately, I haven't been permitted to see the drawing thatgoes along with the question. But I guess that would make it tooeasy. Over here at WikiAnswers we're good, so I'll just answer itwithout the drawing:" . . . the area of triangle AOB."
