What does Tender mean in business?
What does Tender mean in business?
What is tendering? Tendering is a formal process where businesses are invited to bid for contracts from public or private sector organisations, which need specific skills for a project, or goods and services on an ongoing basis.
What does a alternate officer do?
Alternate Designated Officer means an officer of the Adviser other than the Designated Officer. Alternate Designated Officer means the President of the Adviser or an officer of the Adviser other than the Designated Officer.
What is meant by alternate days?
If something happens on alternate days, it happens on one day, then happens on every second day after that. In the sameway, something can happen in alternate weeks, years, or other periods of time.
What is the alternate angle theorem?
The Alternate Exterior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate exterior angles are congruent .
What does a alternate exterior angle look like?
Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. In this example, these are two pairs of Alternate Exterior Angles: a and h.
What is the equation for alternate exterior angles?
Alternate exterior angle states that, the resulting alternate exterior angles are congruent when two parallel lines are cut by a transversal. With reference to the diagram above: ∠ a = ∠ d. ∠ b = ∠ c.
How do you prove alternate exterior angles?
Alternate Exterior Angles Theorem: If two parallel lines are cut by a transversal, then the alternate exterior angles are congruent. The proof of this theorem is very similar to that of the Alternate Interior Angles Theorem.
What is the difference between alternate interior and alternate exterior angles?
Angles that are in the area between the parallel lines like angle 2 and 8 above are called interior angles whereas the angles that are on the outside of the two parallel lines like 1 and 6 are called exterior angles. Angles that are on the opposite sides of the transversal are called alternate angles e.g. 1 + 8.
Are alternate interior and exterior angles congruent?
If lines are parallel then corresponding angles are congruent, alternate interior angles are congruent and alternate exterior angles are congruent. If lines are parallel, then same side interior angles are supplementary and same side exterior angles are supplementary.
Is alternate exterior angles congruent or supplementary?
Alternate exterior angles are always congruent. If alternate exterior angles are congruent then lines are parallel. Alternate exterior angles are on the interior of two lines. Alternate exterior angles are on opposite sides of the transversal.
Are alternate exterior angles are always congruent?
Are vertical angles congruent or supplementary?
Theorem:Vertical angles are always congruent. In the figure, ∠1≅∠3 and ∠2≅∠4. Proof: ∠1and∠2 form a linear pair, so by the Supplement Postulate, they are supplementary.
What happens if lines are not parallel which angle types are still congruent?
The answer for the question is the first option, which is: Vertical. By definition, the vertical angles are those opposite angles that are formed by intersecting lines. Keeping this on mind, if the red lines shown in the figure above are not parallel, the vertical angles of each one them are still congruent.
Why are alternate interior angles equal?
Alternate interior angles are equal if the lines intersected by the transversal are parallel. Alternate interior angles formed when a transversal crosses two non-parallel lines have no geometrical relation. Therefore, the pairs of alternating interior angles are: ∠a & ∠ d.
