3) Geometry: → congruent angles, → congruent circles, → congruent line segments, → congruent polygons, → congruent triangles.

Congruent "suitable, proper," from L. congruentem (nominative congruens) "agreeing, fit, suitable," p.p. of congruere, literally "to come together, agree, correspond with," from → com- "with" + a lost verb *gruere, *ruere "fall, rush."

Damsâz "agreeing, consenting, harmonious," maybe from hamsâz "unanimous," → compatible.

congruent angles
  زاویه‌های ِ دمساز   
zâviyehâ-ye damsâz

Fr.: angles congrus

congruent; → angle.

congruent circles
  پرهون‌های ِ دمساز   
parhunhâ-ye damsâz

Fr.: cercles congrus   

Two circles if they have the same size.

congruent; → circle.

congruent line segments
  برنک‌های ِ دمساز   
borankhâ-ye damsâz

Fr.: segments congru   

Two line segments if they have the same length. They need not lie at the same angle or position on the plane.

congruent; → line; → segment.

congruent number
  عدد ِ دمساز   
adad-e damsâz

Fr.: nombre congru   

Number theory: An → integer N if there exists a → right triangle with → rational sides so that the area of the triangle is N. For example, the number N = 6, because of the 3-4-5 triangle.

congruent; → number.

congruent polygons
  چندبرهای ِ دمساز   
candbarhâ-ye damsâz

Fr.: polygones congrus   

Polygons that have an equal number of sides, and all the corresponding sides and angles are congruent. However, they can be in a different location, rotated or flipped over.

congruent; → polygon.

congruent triangles
  سه‌برهای ِ دمساز   
sebarhâ-ye damsâz

Fr.: triangles congrus   

Two triangles when all corresponding sides and interior angles have the same measure. The triangles will have the same shape and size, but one may be a mirror image of the other.

congruent; → triangle.

conic
  مخروطی   
maxruti (#)

Fr.: conique   

Same as → conic section.

Adj. from → cone.

conic section
  سکنج ِ مخروطی   
sekanj-e maxruti

Fr.: section conique   

A curve which may be represented as the intersection of a plane with a cone; hence a → parabola, → hyperbola, or → ellipse.

cone; → section.

conjecture
  ۱) هاشن؛ ۲) هاشنیدن   
1) hâšan; 2) hâšanidan

Fr.: 1) conjecture; 2) conjecturer, supposer   

1a) The formation or expression of an opinion or theory without sufficient evidence for proof. → mathematical conjecture.
1b) An opinion or theory so formed or expressed; → guess; → speculation.
2) To conclude or suppose from grounds or evidence insufficient to ensure reliability (Dictionary.com).

An opinion or theory formed without sufficient evidence for proof; guess; speculation.

M.E., from O.Fr. conjecture "surmise, guess," or directly from L. coniectura "conclusion, interpretation, guess, inference," literally "a casting together (of facts, etc.)," from coniectus, p.p. of conicere "to throw together," from → com- "together" + iacere "to throw," → eject.

Hâšan, from hâ-, variant ham-, → com-, + šan, from ešândan "to throw out," → eject.

conjugate
  ۱) همیوغ؛ ۲) همیوغیدن   
1) hamyuq (#); 2) hamyuqidan (#)

Fr.: 1) conjugué; 2) conjuguer   

1) An element of a group related to a given element x by y = z-1xz or zy = xz, where z is another element of the group. Also known as → transform.
2) To → inflect a verb.

From L. conjugare "to join together," from → com- "together" + jugare "to join," from jugum "yoke," from PIE *yeug- "to join;" cf. Av. yaog- "to yoke, put to; to join, unite," Mid.Pers. jug, ayoxtan "to join, yoke," Mod.Pers. yuq "yoke," Skt. yugam "yoke," Hittite yugan "yoke;" Gk. zygon "yoke," zeugnyanai "to join, unite," O.C.S. igo, O.Welsh iou, Lith. jungas O.E. geoc.

Hamyuq, from ham- "together," → com- + yuq "yoke," from PIE *yeug- "to join," as above.

conjugate angles
  زاویه‌ها‌ی ِ همیوغ   
zâviyehâ-ye hamyuq

conjugate complex number
  عدد ِ همتافت ِ همیوغ   
adad-e hamtâft hamyuq (#)
